Tips For Protecting Yourself From Computer Viruses

Computer viruses are a common cause of many computer problems and malfunctions. Unfortunately, computer viruses can spread very easily if your computer is not properly protected. And left untreated, a computer virus can make your computer essentially unusable! Having a virus can also open you up to a host of other related issues, including identity theft and email hacking. So it's obviously extremely important to protect yourself from viruses.

But many people are unsure as to how best to protect themselves from computer viruses. There are so many different anti-virus products available that it can be difficult to choose one. The good news is that many anti-virus programs work in the same way -- by preventing the virus from infecting key system files within your computer. Infection can occur simply by visiting an infected website or downloading a file that has the virus. The virus is often kept "isolated" on your computer, thus allowing you to delete the virus at any time with no risk to your system.

That said, the most critical aspect of successfully using any anti-virus program is keeping the program's virus definitions up-to-date. New computer viruses are created constantly, so it's vitally important to make sure that your system is protected against the latest threats. A good anti-virus program will update automatically, so make sure not to disable this important feature or you could be leaving your computer vulnerable to new virus threats. In most anti-virus programs, you can change a setting within the program that affects the time each day that the program will automatically check for new virus definition updates, so you can change this task to be done during a time when your computer will be online. It won't do any good to set your virus definitions to update at 3 AM each night if you always turn your computer off overnight.

Another aspect of preventing computer viruses is avoiding websites that are likely to harm your computer. The search engine Google will alert you if a search result will take you to a website that has been reported to contain viruses, Trojans, malware, or other programs that are likely to attack your computer. Websites offering "free downloads" are often sources of malicious software that can harm your computer, so avoid these types of websites unless you already know the site is legitimate.

Additionally, many viruses spread through email, especially through attachments, so do not download email attachments sent by people you don't know. Email viruses can even be sent by people you know and trust -- one of the main ways computer viruses spread is through an infected computer automatically sending a virus-infected email to everyone in the infected computer's email contacts list. If an email attachment seems suspicious, try doing a Google search for the file name or the subject line of the email. That way, you can find out if the seemingly harmless attachment is actually a harmful computer virus.
