How to protect computer from virus

There are many kinds of viruses, and many ways that viruses may infect your computer system, including installing software or booting your computer from floppy disks or CD-ROMs, however the most likely cause now is virus infection via your Internet connection, specifically from email, browsing the web, and downloading software from the Internet. There are some simple rules to follow which will minimise the possibility of being caught out. 

Protect Computer From Virus

1. Never open a file attachment sent to you from an unknown source. In most cases, the safest thing to do is delete them as soon as you see them in your mailbox. 

2. Understand that patches and updates for programs are rarely distributed by email. (Microsoft and other reputable companies use other means, which are more secure.) 

3. Never open a file unless you know what it is. If you've received it from someone you know, ask him or her about it. (They may have a virus infection that is mailing out copies of itself without their knowledge.) 

4. Files containing virus content are always sent disguised in some way. For example, the message may say a screensaver, bill or invoice is attached. 

5. Users of Outlook and Outlook Express should disable the Preview Pane. A recent virus was thought (but not proven) to infect simply by being displayed in Outlook Express. It is be safer to avoid any risk! 

6. Always use Windows Update to ensure that the latest security patches from Microsoft are installed on your system. If you don't do that then make regular visits to Microsoft's web site to check for update patch availability. (Go to www.microsoft.com and select Windows Update from the left side menu. 

7. Last, and most important, every computer must have anti-virus software installed and running whenever the computer is switched on - and without fail, the virus definition programs should be kept up to date each and every week. Some programs such as McAfee AntiVirus or AVG can be configured to automatically check for updates several times a day while some programs require manual updating by connecting to the product update site. If you have not updated your viral signatures recently then go to the program supplier's web site and download any updates now!



There's one know way to protect yourself 100% from viruses. 

Don't allow anybody on your computer, do not download anything onto your computer, and do not connect your computer to any network or internet connection. 

You'll be 100% safe then and that's the only way.
