generally antivirus try 2 delete or corrupt ur system files.it trys 2 isolate ur system.
it searches your pc and isolates any viruses before deleting them.

if there was no anti virus software then most pc's would be knackered because a virus is a malicious program that people write to destroy or "attack" peoples pc's which can then destroy information and programs that will stop a pc from functioning
it do what it is designed to do

and what it is suppose to do
so find virus and others find them and delete them
