Because I use Linux, I take a cavalier attitude towards viruses. Probably not a good idea, but really, when did we ever have a major virus outbreak in the wild for Linux. Okay, I'll shut up now, because I don't want to jinx the system.
On the other hand, Linux theoretically makes a good platform for checking for Windows virus infections. I say theoretically because in the end, it all depends on the engine and signature files. What I've seen recommended in many sites is ClamAV; again, there may be pros and cons in the discussion, but I'll leave that to the experts.
ClamTK is the front-end for ClamAV. Simple enough to understand.
I'll try to catch a virus one of these days and report it here.
