How does a Anti virus work
hi there, can anybody tell me how does a anitivirus work (in detail plz) coz i know that a AV scans through a file searching for the mention of the words .exe and .com
but how does it remove it ??? does it take a backup of the original file and then compare it???
eg. if a dll is detected then how does norton delete it and replace with the original one
????
PLZ help
