Well there are some other measures for detecting it and geeks know it better than me but ever you thought about what is a computer virus.
A virus is nothing but a script that gets on the RAM of the system and executes with any program that it finds suitable, spread from peer to peer , example Code Red worm which replicated more than 250,000 times in just 9 hours. Another example of virus is Boot sector virus which gets loaded in boot sector of the hard disk or floppy and get executed every time system is turned on, since the hard boot sector is used when the operating system loads .
Well there are many ways in which one can get the system virus free to some extent is by following some tips :
