Some don't use an Antivirus. Do you?
There are also other than Virus items out there that an antivirus will not deal with. In the general category of PARASITES are malware that does damage to the OS, but is not viral or trojan and the antivirus doesn't deal with it since... "it's not a virus".
Tools like Adaware, Spybot will detect and remove much but not repair associations. For that, try IEFIX. Look up IEFIX on google.com
