What is the best malware removal people happily using on their DAW's and is there a general consensus about what's good, lightweight Windows antivirus software? I'd like something that uses few resources, offers decent protection, and is unobtrusive(!!!).

Obviously, my DAW is connected to the net and it will remain that way, so I'm not interested in any "don't connect it to the net" type comments.

I've been using BitDefender, but I really don't like all the extra bells and whistles (safe pay, search results scanner, etc.) or the pop-ups/advertisements. So what else should I be looking at now that my license is about to expire?
