Alright fags, I have a torrent question for you.

I downloaded objectdock plus from piratebay, but before I unrar'd it, I scanned it with Sophos AV. It detected malware, but is it possible it could consider the keygen to be malware, even tho it isn't?
The reason I ask is because it is the highest seeded torrent for this software on piratebay, and there are plenty of comments from other people saying it is legit.
