How to tell if a false positive or not?

[FireMyst]

HI everyone,

I recently ran a scan with Malwarebytes' AntiMalware and it came back with 7 files "infected" -- 3 were Riskware, 2 were Trojan.FakeAlert, 2 were Malware.Packer.Gen.

I've used these files before, and haven't noticed any problems with my computer.

These 7 files are keygen like files which apparently are susceptible to being recognized by anti-virus and anti-malware programs as infected.

They survived Norton and McAfee scans. Is there any way to tell if these files are really infected? Or just a "false positive" (which I'd hate to submit if it's not really false).

Thanks!

We will not be assessing the safety of cracks and keygens.
