REASON 4- Viruses-

Often the first sign of a virus infection is instability. Some viruses erase the boot sector of a hard drive, making it impossible to start. This is why it is a good idea to create a Windows start-up disk. Go to


* Start-Settings-Control Panel-Add/Remove Programs


Here, look for the Start Up Disk tab. Virus protection requires constant vigilance.


A virus scanner requires a list of virus signatures in order to be able to identify viruses. These signatures are stored in a DAT file. DAT files should be updated weekly from the website of your antivirus software manufacturer.


Some good antivirus software are...
1. AVG ( http://www.freeavg.com/?lng=in-en&cmpid=free )
2. McAfee ( http://www.mcafee.com/us/ )
3. Norton ( http://antivirus.norton.com )
