But what I'd try is a disk cleanup, then reboot into safe mode and run a full AV scan.
(If it happened on my computer I'd be using different on board tools for it, but that's another story...you have to work with what you've got.)
If no luck with that method, try downloading the rather excellent http://www.superantispyware.com/
install, update, and run a full scan with that one.
Quarantine anything found,rather than delete.
My Symantec Antivirus always gives below notification. Totola number of notifications is over 2000 and still increasing. how can i delete this virus.
