bywinners,men

I have just got a bywinners,men (dot not comma) advert popping up on my pc. It seems pretty dodgy, but I haven't installed anything that I know about and McAfee can't find anything.


googling suggests its malware but the links aren't familiar.

Does anyone know a good malware checker?
