I just downloaded and installed the game. Right after I was done with that my antivirus (avira antivir) gave me a warning regarding the file dvm.dll, which appareantly has a trojan horse inside it, named "TR/Obfuscate.XZ.4858".
A quick google search brought me to this forum page: http://www.gog.com/en/forum/patrician_series/virus_infection_false_positive/?staff=yes
I assume this is the same problem?

this is being discussed at http://www.gog.com/en/forum/chronicles_of_riddick_the/tages_drm

Ah, I didn't see that. Thank you.
