It's incredibly annoying when antiviruses detect harmless game hacks with names that don't reflect that. If it's called GameHack.Trainer.sgfd, it's fine. But when they call it "Trojan.Malware.sgfd" I think that's really annoying. Don't flag it as malware if it's not really a malware. In the end users can't be sure if it's really a malware or just potentially unwanted app which actually isn't malicious, but not all would want it. So you know you can still use it because it's not actually malicious.
Considering the VT ratings, it seems like it's really just a trainer and not malware posing as one. Excluding it should do the trick. Should be classified as PUP and not as Win32:Rootkit-gen...
