Hey guys, whats the best online virus scanner thats free? my work pc has shit itself and email and i.e is running so bad n freezing etc

i cant even open new emails or reply to emails etc... keeps freezing then not responding.

Ive used AVG for years and haven't had a problem.

I don't trust any that offer to scan your PC without you downloading and installing as it involves opening up your PC to the scanner over the net.
Over the years I've used several free ones, Avast, Avira, and more recently AVG, but currently I'm trialling the Comodo free security suite and I'm fairly impressed with it.
