If any of you download trainers from here, I have experienced some "rogue" trainers to be infected.
I suggest you only download the trainers this site makes for you.(Unlimited Member) Scan all the other trainers you have downloaded from this site.
here's a online scanner (if you don't have anti virus) keep in mind tho, the minute you went with explorer to the trainer you are infected. So uploading the trainer to the online scanner will get you infected, but this is needed to know if the trainer is infected.
