For a long time now I have problems with Amiga emulator and games downloaded from thecompany.pl web site. Avast always finds some Win32:Adware-Gen (so, something suspicious, OK), but when I upload file to virustotal, Avast doesn't react there, and of 40 or so AV programs, only 2 or 3 reacts with something generic.
Try, for example, this:
http://thecompany.pl/game/WalkerYou can't even download it.
Please, research some of these and if there is adware there, name it, don't just get generic name
and I am sure there isn't anything dangerous, just preconfigured Amiga emulator with amiga games packed into self extracting file.
