Good antivirus softwares?

my computer doesnt have any antivirus software installed.

I know that its now infected with the TROJ_HIDER.I virus !

(because it was found in my thumb drive)

Please tell me whats the best and latest antivirus software i should install?

What are the latest McAffee and Nortans versions?

importantly, the scanner should be able to detect the TROJ_HIDER.I virus and clean it.
