How to Avoid Getting Ripped-Off Online
Online security is one of the top catch phrases these days, but hardly anybody knows what it means and worse, most home computer users think security only applies to corporations and online businesses. Most people think online security means simply protecting your credit card data from fraud and theft, but it actually goes way beyond that. The potential for mayhem and just plain disruption of your life doesn't just mean credit card fraud - it can mean having your identity stolen, your life disrupted and spending hours cleaning up after an online 'vandalism' attack. You must protect yourself from everyone from the teenage computer hacker to the organized crime syndicate using computer worms and keystroke logging viruses. The great news is that a number of simple techniques should protect you against the vast majority of threats, since the evil doers will simply move on to easier pastures. Update your anti-virus files The widespread 'Bad Trans' worm logged keystrokes and transmitted potentially sensitive data such as credit card and social security numbers to the 'bad guys'. Though this virus contained a high level of criminal intent, it was easily blocked by anyone with up-to-date anti-virus files. If you don't have anti-virus software with current virus definitions installed, you leave the door wide open for security problems. Install a 'Firewall' A firewall helps prevent unauthorized access to your computer by 'hackers'. It closes off the entry points (called open 'ports') carried by virtually every computer connected to the Internet. A common misconception is that firewalls are only for people with cable or other high-speed connections. Even if you use a dial up connection to get online, a firewall can help you detect and prevent people from logging on to your computer, stealing files or even using your computer to break into others! You can take a free test of your computer's security by logging on to http://www.symantec.com/securitycheck/ and clicking 'Find out today if you are safe'. The results may surprise you. Use secure sites Only give sensitive data such as credit cards, social security numbers and important passwords over a secure connection. This means the little yellow lock appears in the lower part of your browser and nobody but the website you are connected to should be able to read the data you send. Change passwords often An easy way for you to protect your sensitive data and email is to change your passwords on a monthly basis, or even more often depending on how frequently you use computers away from home. If you log on to your email at the library, in 'cyber cafes' or any other remote computer then the possibility exists that computer could have a key-stroking virus present. This means everything you type into the computer (passwords, birthdays, social security numbers, credit cards) could be logged and used by someone else. ** Change your passwords at lease once a month. Though not fool-proof, these security tips should help reduce your vulnerability and keep you safer online. |

All About Computer Viruses
Your computer is as slow as molasses. Your mouse freezes every 15 minutes, and that Microsoft Word program just won’t seem to open. You might have a virus. Just what exactly is a virus? What kind is in your computer? How did it get there? How is it spreading and wreaking such havoc? And why is it bothering with your computer anyway? Viruses are pieces of programming code that make copies of themselves, or replicate, inside your computer without asking your explicit written permission to do so. Forget getting your permission down on paper. Viruses don’t bother to seek your permission at all! Very invasive. In comparison, there are pieces of code that might replicate inside your computer, say something your IT guy thinks you need. But the code spreads, perhaps throughout your office network, with your consent (or at least your IT guy’s consent). These types of replicating code are called agents, said Jimmy Kuo, a research fellow with McAfee AVERT, a research arm of anti-virus software-maker McAfee Inc. In this article, though, we’re not talking about the good guys, or the agents. We’ll be talking about the bad guys, the viruses. A long, long time ago in computer years, like five, most viruses were comprised of a similar breed. They entered your computer perhaps through an email attachment or a floppy disk (remember those?). Then they attached themselves to one of your files, say your Microsoft Word program. When you opened your Microsoft Word program, the virus replicated and attached itself to other files. These could be other random files on your hard drive, the files furthest away from your Microsoft Word program, or other files, depending on how the virus writer wanted the virus to behave. This virus code could contain hundreds or thousands of instructions. When it replicates it inserts those instructions, into the files it infects, said Carey Nachenberg, Chief Architect at Symantec Research Labs, an arm of anti-virus software-maker Symantec. Corp. Because so many other types of viruses exist now, the kind just described is called a classic virus. Classic viruses still exist but they’re not quite as prevalent as they used to be. (Perhaps we could put classic viruses on the shelf with Hemingway and Dickens.) These days, in the modern era, viruses are known to spread through vulnerabilities in web browsers, files shared over the internet, emails themselves, and computer networks. As far as web browsers are concerned, Microsoft’s Internet Explorer takes most of the heat for spreading viruses because it’s used by more people for web surfing than any other browser. Nevertheless, “Any web browser potentially has vulnerabilities,” Nachenberg said. For instance, let’s say you go to a website in IE you have every reason to think is safe, Nachenberg said. But unfortunately it isn’t. It has virus code hidden in its background that IE isn’t protecting you from. While you’re looking at the site, the virus is downloaded onto your computer, he said. That’s one way of catching a nasty virus. During the past two years, another prevalent way to catch a virus has been through downloads computer users share with one another, mostly on music sharing sites, Kuo said. On Limewire or Kazaa, for instance, teenagers or other music enthusiasts might think they’re downloading that latest Justin Timberlake song, when in reality they’re downloading a virus straight into their computer. It’s easy for a virus writer to put a download with a virus on one of these sites because everyone’s sharing with everyone else anyway. Here’s one you might not have thought of. If you use Outlook or Outlook Express to send and receive email, do you have a preview pane below your list of emails that shows the contents of the email you have highlighted? If so, you may be putting yourself at risk. Some viruses, though a small percentage according to Nachenberg, are inserted straight into emails themselves. Forget opening the attachment. All you have to do is view the email to potentially get a virus, Kuo added. For instance, have you ever opened or viewed an email that states it’s “loading”? Well, once everything is “loaded,” a virus in the email might just load onto your computer. So if I were you, I’d click on View on the toolbar in your Outlook or Outlook Express and close the preview pane. (You have to click on View and then Layout in Outlook Express.) On a network at work? You could get a virus that way. Worms are viruses that come into your computer via networks, Kuo said. They travel from machine to machine and, unlike, the classic viruses, they attack the machine itself rather than individual files. Worms sit in your working memory, or RAM, Nachenberg said. OK, so we’ve talked about how the viruses get into a computer. How do they cause so much damage once they’re there? Let’s say you’ve caught a classic virus, one that replicates and attacks various files on your computer. Let’s go back to the example of the virus that initially infects your Microsoft Word program. Well, it might eventually cause that program to crash, Nachenberg said. It also might cause damage to your computer as it looks for new targets to infect. This process of infecting targets and looking for new ones could eventually use up your computer’s ability to function, he said. Often the destruction a virus causes is pegged to a certain event or date and time, called a trigger. For instance, a virus could be programmed to lay dormant until January 28. When that date rolls around, though, it may be programmed to do something as innocuous but annoying as splash popups on your screen, or something as severe as reformat your computer’s hard drive, Nachenberg said. There are other potential reasons, though, for a virus to cause your computer to be acting slow or in weird ways. And that leads us to a new segment – the reason virus writers would want to waste their time creating viruses in the first place. The majority of viruses are still written by teenagers looking for some notoriety, Nachenberg said. But a growing segment of the virus-writing population has other intentions in mind. For these other intentions, we first need to explain the “backdoor” concept. The sole purpose of some viruses is to create a vulnerability in your computer. Once it creates this hole of sorts, or backdoor, it signals home to mama or dada virus writer (kind of like in E.T.). Once the virus writer receives the signal, they can use and abuse your computer to their own likings. Trojans are sometimes used to open backdoors. In fact that is usually their sole purpose, Kuo said. Trojans are pieces of code you might download onto your computer, say, from a newsgroup. As in the Trojan War they are named after, they are usually disguised as innocuous pieces of code. But Trojans aren’t considered viruses because they don’t replicate. Now back to the real viruses. Let’s say we have Joe Shmo virus writer. He sends out a virus that ends up infecting a thousand machines. But he doesn’t want the feds on his case. So he instructs the viruses on the various machines to send their signals, not of course to his computer, but to a place that can’t be traced. Hotmail email happens to be an example of one such place, Kuo said. OK, so the virus writers now control these computers. What will they use them for? One use is to send spam. Once that backdoor is open, they bounce spam off of those computers and send it to other machines, Nachenberg said. That’s right. Some spam you have in your email right now may have been originally sent to other innocent computers before it came to yours so that it could remain in disguise. If the authorities could track down the original senders of spam, they could crack down on spam itself. Spam senders don’t want that. Ever heard of phishing emails? Those are the ones that purport to be from your internet service provider or bank. They typically request some information from you, like your credit card number. The problem is, they’re NOT from your internet service provider or your bank. They’re from evil people after your credit card number! Well, these emails are often sent the same way spam is sent, by sending them via innocent computers. Of course makers of anti-virus software use a variety of methods to combat the onslaught of viruses. Norton, for instance, uses signature scanning, Nachenberg said. Signature scanning is similar to the process of looking for DNA fingerprints, he said. Norton examines programming code to find what viruses are made of. It adds those bad instructions it finds to its large database of other bad code. Then it uses this vast database to seek out and match the code in it with similar code in your computer. When it finds such virus code, it lets you know! |
5 Sure-Fire Tips for Buying a New Computer
So you're thinking of buying a new computer... Where do you start? There are so many brands and models of computers available, and it can all be a little overwhelming when you start to look around. How do you decide what type of computer you need? And perhaps more importantly, how do you decide what the best value is? I have sold computers professionally for almost 20 years, and there are certain "tricks of the trade" that most computer stores and salespeople use. Knowing these secrets can make your decision easier and will help you buy the right computer for your needs. 1. Buy What You Need, Maybe a Little More One of the most important things you can do when buying a new computer is make a list of the things that you will be using it for. There are so many different models - with different capabilities - that you can easily buy more, or less, than you really need if you don't. If this is your first computer, this can be a little tougher. Until you've used a computer, it's hard to know exactly what you might want to do with it beyond the obvious, like connecting to the internet. Regardless, you should think about some of the things you might want to do. Some possibilities include: - Connect to the internet - Play games - Digital photography - Digital video - Type documents - Accounting - Design websites - Programming - Digital scrapbooking - Geneology Some of these things need more power than others. For example, connecting to the internet really doesn't need a lot of power. Even the most basic computer available will probably work just fine. Digital video and many games need a lot more power. If you don't get a fast enough computer with enough memory, you'll be disappointed with the performance. Knowing what you're going to be using your computer for will help your salesperson, whether they're on the phone, the internet or standing in front of you, recommend the best system for your needs. As a general rule you're always better off buying more power than you need rather than less, but buying too much can be a waste of money. 2. Warranty Considerations Computer warranties are one of the most confusing and obscure parts of your purchase. Most manufacturers have cut back on their customer service to the point where poor service has become a given. The three most common options are onsite, carry-in or manufacturer's depot service. Onsite service can be helpful, but think about whether you want to have to be available for a technician to come and diagnose your computer, and possibly have to come back with parts at another time. Carry in service is a good option, but find out whether the service center is factory authorized for warranty repairs, as well as whether the technicians are all certified. Shipping your computer to a factory service center can take a long time - sometimes a number of weeks. It also creates risk that your computer will be damaged or even lost in shipping. In some cases, the manufacturer will even replace your computer with another unit and ship it back to you, rather than repairing it. This can result in your losing any information that was on your system and having to reload all your software. Another aspect of the warranty to find out about is technical support. Find out if the computer manufacturer offers a toll-free phone number and what the quality of service is like. The better computer salespeople will be honest about this and tell you if a company's service leaves something to be desired. You can also do some research on the internet - most of the computer magazines like PC Magazine and PC World have annual customer service comparisons that rate the larger computer companies. Always find out how the warranty is handled before making your decision. Even if it doesn't influence your choice, knowing what to expect if something does go wrong will save some nasty surprises down the road. 3. Can You Negotiate the Price Down? A computer is a relatively large investment - anywhere from a few hundred to a few thousand dollars. Many computer buyers expect that there is a significant amount of "wiggle room" on the price. The reality is that most computer hardware - the physical pieces like the computer, monitor and printer - is sold at very low profit margins. Often, computer systems are even sold at or below the dealer cost. When you're buying a computer, it never hurts to ask for a better deal, but don't be surprised if you only get a few dollars off, if anything. Over the close to 20 years I've sold computers, I watched the profit margins go from over 40% to less than 5%. It's almost embarassing to offer a $20 discount on a $2500 computer system, but that could mean the difference between making and losing money on the sale. What you can do to get the best price is to do some comparison shopping. Most computer stores offer price-matching guarantees, so if you find your computer for less at another store, most dealers will match or beat that price, even if it means they lose money. 4. How Do Computer Stores Make Any Money? You might be wondering how these computer stores make any money if they're selling computer for so little profit. Their money is made on add-on items. The highest profit areas in most computer stores are cables and "consumable" products such as printer ink and paper. Printer ink is a huge money-maker for most computer stores (even more so for the printer manufacturers). Why is this? Once you've bought a printer, you're going to have to replace your ink at some point, and continue to replace it as it runs out. Most chain computer stores and office supply stores that carry a large selection of ink cartridges make more from ink than they do from the computers themselves. Cables also have huge markups. A cable that costs the store $2-3 will often sell for $20-30. That's ten times their cost! If you're buying a new computer, you will likely need to buy some cables. Some items - printers, for example - don't often include the cables needed to hook them up. Many printers also come with "starter" ink cartridges that are only half-full. You might also want to pick up some extra ink cartridges. This is where you should be able to negotiate a better price. Don't expect the salesperson to throw them in for nothing, but they should be willing to offer you a better price. After all, if you're happy with their service, you'll probably continue to buy your ink, paper and other products from that store in the future. 5. What Software is Included? The last secret of buying a new computer has to do with the software that is included. Most new computer systems include quite a few programs and sometimes the value of the software can be quite high. Something to watch out for when looking at the included software is "trial versions" or "limited editions". Many programs that are preloaded are either crippled versions that don't have all the features of the full program, or trial versions that will only run for a certain amount of time before they expire. Computer are often sold with trial versions of the following types of software: - antivirus - firewall - MS Office or other office suites - Accounting - both business and personal The computer manufacturers generally don't make it easy to tell whether the software on their systems are trial versions or limited versions. This is a question that you should specifically ask if you can't find the answer in their promotional information. If you're buying a new computer with trial versions of the software, keep in mind that you will need to pay to continue using it after the trial period is over. This is an added cost that you need to consider as part of your overall budget. These five "secrets" of buying a new computer are fairly common sense, but they are not always made clear up front. Knowing what to ask will help you in two ways. First, you can be sure you are getting the right computer for your needs. Second, if the salesperson or company that you're dealing with explains these things to you without being asked, you'll know you're dealing with someone who is honest and upfront. Knowing you can trust the people you're dealing with is an invaluable feature of your new computer system. |

Top 10 Ways To Protect Yourself From Computer Viruses
As more and more people are becoming comfortable using their computers at school, home or in the office it’s only a matter of time before they encounter a computer virus. Here are our top 10 steps to protect you from computer viruses. Use a high quality anti-virus program. There are many different anti-virus computers programs on the market some of them are better than others. Look to reputable computer magazines or websites for ratings to help you find the one that matches your needs. Always use your anti-virus software. Make sure your anti-virus software is always turned on and scanning, incoming and outgoing email messages, and any software programs you run. Keep your antivirus programs up to date. Most programs come with a yearly subscription make sure you take advantage of the updates. More advanced programs allow you to schedule updates or full system scans for “off hours” like 2AM when you aren’t likely to be using your computer. Keep your computer up to date. From time to time operating systems fall victim to security holes or issue updates. Make sure you check periodically to make sure you are running stable up to date versions of your software. Backup your data regularly. Most windows computer users keep their documents in the “My documents” folder. This makes it easy to back up all of your important documents. Make weekly or monthly copies to CD or USB drives. If you use floppy disks or USB drives on public computers like your school computer lab, Kinko’s, or even digital photo printing store make sure you scan them for viruses. Public computers are notorious for not being up to date and properly protected. Be wary of email attachments. Treat any email attachment as potentially dangerous. Never open attachments from people you weren’t expecting. Also be careful of attachments from people you know but weren’t expecting. Many computer viruses replicate themselves by reading the contacts from an infected computer. Use text email if possible. While HTML email is prettier and allows you more control over formatting it also can carry computer viruses. If you use text based email the only way to get a virus is by opening an attachment. Use downloaded freeware and shareware files or software with caution. Try to download them from popular reputable sources that scan the programs before they are uploaded. To make sure you are safe scan the program before you install it on your computer. Be wary of links in IM or instant messaging software. Don’t accept invitations from people you don’t know and never click a link from someone you don’t trust, they can easily redirect you to another website that will try to install a virus on your computer system. |

Business WebSite Content Strategy
Web Content Strategy: Sources of Content
There are four basic ways you can get content for your site:
1. Licensed content that you can publish on your site for a one-time or recurring subscription fee, or in exchange for putting a link to the author's site under the article. The main benefit of this kind of content is that you can build up your site quickly. The drawback is that hundreds if not thousands of other sites will be publishing the same content, which means you will get little search engine traffic from it. Also, within a few years, the subscription fees or the value of visitors who leave via the required link to the author's site will amount to more than you would have paid to have original content professionally written.
2. Original content contributed freely by your visitors, such as message boards and guestbook-style comments. The main advantage of this content is that it costs nothing and gives you insight into your visitors. The disadvantages are (usually) low quality and the constant vigilance needed to police it for misbehavior.
3. Original written content that you allow other sites to republish in exchange for a link to your site. This content is usually informational articles, whitepapers, and sometimes, press releases. Distributing content is an essential component of getting links to your site.
4. Original, well-written content that's exclusive to your site. You should have some content that you hold back from republication, to avoid giving visitors or search engines the idea all your content can be had somewhere else. This can include FAQs, "about us" pages, case studies, testimonials, and other content that other sites would not want to reprint anyway.
What Kind of Content to Use
So, which of the four kinds of content should you use on your site? Ideally, all four. That way you'll maximize the amount of quality content your site can have.
But, the precise ratio of the four kinds of content you end up using will depend on the goals of your site. Some examples:
* Licensed content: If you have a content-based website that draws revenue from advertising, a large amount of licensed content can be useful. However, if your site's primary goal is to collect leads, too much licensed content might risk distracting visitors from contacting you, without the benefit of bringing in significant search engine traffic.
* User-contributed content: A website that handles support issues may have a lot of use for a user forum. A professional services firm would probably be better off without a forum, with all the user-contributed content in the form of testimonials.
* Original written content, exclusive and for distribution: Any website can benefit from original content since it draws search engine traffic and puts your best foot forward with visitors. The broader your potential audience and the greater the competition from other sites, the more content you need.
Scheduling Content Updates
Search engines, especially Google, seem to give pride of place to sites that regularly update their content. Regular content updates also give visitors a reason to return.
In short, if you have thirty web pages worth of content this month, it's better to post one page each day rather than put them up all at once. To make sure you do this, schedule an hour each day for updating your site's content.
One way to get regular content updates for your site is to start a blog, a "web log" in which you write your thoughts and post news. The one disadvantage is that many web users are getting tired of blogs, which are often not well written and contain more opinion than information. Search engines, too, seem to be featuring blogs in their results less often.
Identifying a Content Provider
Ever wonder how Bill Gates keeps the MSN and Microsoft sites so content-rich? Doesn't he get RSI from writing a thousand or more pages a day?
You guessed it: Bill Gates does not write the content for any of the Microsoft websites. Nor should you write all your own content. All successful website owners have someone else write a large part of their content. This person or company is often called a "web content provider" or "website copywriter."
You need to select a web content provider with proven experience writing content for the web, rather than just writing for print. Ask to see writing samples. You might even ask if you can commission just a single page to start with, for evaluation purposes. Also make sure that you are buying all rights to the content.
After all, the most important part of your website content strategy should be quality.
Five Ways To Win The Favor Of Search Engines
How do you make your website known? How do you make yours stand out among millions of others? You can spend lots of money on advertisement, but that will not work if you don’t have the money to spare on advertising. So what do you do? Make search engines work for you, that’s what!
Google, Yahoo, MSN, Lycos, Altavista - you want to be at the top of their results list. The higher your site is in a search results page, the better chances that it will be visited. The science behind making your site a popular search result is called Search Engine Optimization (SEO). Don’t worry, though - even if SEO is referred to as a science, it is not all that complicated. You just need to take note of a few things, and before you know it, your site will have more visitors than you could ever dream of.
Here are five tips to ensure that your site would be a favorite of search engines all around the cyber world.
1. Give importance to substance over appearance.
Do you want to share your knowledge on a subject that you have authority on? Do you want to sell products? Do you want to build an online shrine for your favorite actress? Whatever topic you have chosen for your website, make sure that you are able to give useful information on it. Search engines work by scanning sites for keywords. They search text and completely ignore everything else. So if you have made your site rich in colors, don’t forget to make it rich in content as well. After all, a beautiful layout can make people look, but relevant content is what will make them stay. Remember, in this day and age: content is king!
2. Know your topic well
If you know much about your topic, you will know what people usually ask about it, and what they ask about it is what they will type in the search bar. When writing the content for your website, put yourself in your other people’s shoes, people who will be your target audience or market. Know the possible questions they might have about your topic, and give answers in your site.
3. Learn from the best
Take time to browse and read sites that get lots of visitors and have the same topic as yours. Take note of any recurring phrases in these sites’ text. These phrases are most likely keywords. Incorporate them in your own site’s content. Don’t saturate your site with keywords, though. You don’t want to sound redundant to your site visitor. A 3 ensity level would be enough.
In searching for the right keywords, use Overture’s services. It may take quite some time, as it is more of a trial-and-error method, but the results are conclusive, and a pattern can easily be observed.
4. Submit…and re-submit
You will never get a certain job if you don’t send in your application for it. The same thing applies to SEO. If you want your site to be recognized by search engines, then go out of your way to register your site with them. After a couple of weeks, search for your site by putting in the keywords you used in your content. If your site is still not coming up in the search results, do not give up, and just re-register and resubmit your site. It’s possible that your initial registration was discarded without being processed. This usually happens because a lot of submissions are being done everyday.
5. Constantly update your site
This can’t be stressed enough: search engine spiders love sites which constantly change their content. You can’t build your site and expect it to last forever without any updates. There will come a time when those search engine spiders would stop fetching your site for query requests. Here’s a tip: integrate a blog program in your site. Blogs have a user-friendly interface that allows easy updates.

This Heart Attack Symptoms in Women
According to the results of the study found, some doctors are giving less inspection, less frequent follow up, fewer treatments and less surgery in women. Perhaps this is why heart attacks more deadly if it happened to women than men.
Well, to find out more about what the early symptoms of heart attack in women, see the following reviews.
Difficulty breathing
If you often feel shortness of breath during sitting and even sleeping, maybe there is something wrong. Shortness of breath accompanied by sweating and dizziness usually a sign of a heart attack. Be careful, because these symptoms can cause fainting.
Limp for no reason
Feeling weak and tired is normal if you are experiencing stress at work. But if you feel weak and tired more than usual, you may be experiencing a heart attack. Before and during the attack, your heart will stop pumping properly, resulting in oxygen and glucose spread throughout the body. The result, you will feel very weak.
Trouble sleeping
Experts say that the disorder is difficult to sleep is a symptom of a heart attack that many experienced women. When obtruktif experience sleep disturbances, upper respiratory tract is blocked as a result of respiratory impaired that heart attacks are more likely to occur.
According to the study, women who suffer from heart disease go through this a month before a heart attack. So if you often wake up at night, sweating and unable to regulate the breath, see your doctor immediately.
Indigestion
In one study of women known to two times more likely to experience vomiting, nausea and indigestion for several months before a heart attack than men. This condition occurs due to blockage in the arteries of fat will reduce blood supply to the heart that typically occurs in the chest can sometimes arise in the stomach.
It depends on which part of the heart is broken, so he sends pain signals in the lower part of the body from the chest.
Some ways you can do to prevent heart attacks such as keeping cholesterol, blood lipid levels, in order to maintain blood pressure control, quitting smoking, avoiding fatty foods, living on fruit and vegetable consumption, exercise regularly, lose weight and reduce stress.
Nausea and vomiting
As a result of your body in a state of 'emergency' during a heart attack, the nerves that control body functions to work too hard. This will make you often sweating, pallor, dizziness, nausea and often vomiting. Experts do not know the exact reasons behind this situation, but if you frequently experience this, it's good to see a doctor immediately.
Some body feels uncomfortable
Logically, a heart attack will attack and give effect to the left side of the body, especially the left arm. But one sign of a heart attack are pain and discomfort in the left arm or both arms. Pain and discomfort is also felt in the jaw, neck, back and stomach as well.
Computer Error? Do not hastily Reinstall
Reinstall the operating system is the easiest way. Before doing so it's worth finding first solution. During the problem limited to the application or the operating system alone, this can be easily resolved with the help of an application system repair.
Here are some examples of problems that are often found in computer systems and their causes:
1. Display a blue screen (Blue Screen of Death)
Display BSOD is most frustrating moment happens to your computer. Inevitably you have to reboot, the severity of this can happen when you do not save the jobs that have been made previously. This message has the intention to notify any errors that occur by displaying certain codes. Most of this is caused by hardware that is beginning to show symptoms of unhealthy or any problems with the drivers.
2. DLL files are missing
File Dynamic Link Library (DLL) is an information center of the operating system that functions to perform various functions. DLL files are missing can be caused by errors in the installation process or file damage due to viruses and other things.
3. Applications that do not want installed
If an application is not installed or it is always a failure, it could be because your computer does not have enough hard drive space. In this case, you need to free up space on your hard disk by deleting files or folders that are not important or already have a backup.
4. The application is running slow
There are several reasons why this could be happening. But mostly it comes from the operating system or applications installed. The number of hidden applications that run concurrently or irregular placement of files and folders can be the cause.
5. Application behavior is not normal
When running an application, all of a sudden some functions may not work properly. For example, Microsoft Word is experiencing hangs when activating a function. This could
caused by damage to certain files or clashing with other files. Usually you have to do to update or reinstall the application.
Most of the repair system application handles the above problems in an easy and fast. Even some of these applications have additional features to enhance overall system performance.
