Question regarding Overlord II +10 trainer.

[Nue7ra1]

So, I have this habbit running everything I download through several anti-spyware/virus/malware programs, and the results in the attatched image came up while I was scanning http://m0004.gamecopyworld.com/games...0+10%20TRAINER .

Normally, I wouldn't be to worried, considering this site's pretty good track record of catching malware, but the part where some of the AVs they used are saying "worm" has me concerned, if only becuase I haven't seen a trainer come up as "worm" before. So, my question is, should I be worried about this? Or is it showing up as worm because of some code injection deal that would go straight over my head?
