Win32:Malware-gen False Positive?

[Fraks Cap]

Hi,
Yesterday i bought the Witcher and decided to mod it. The most popular mod that i wanted was The Rise of the White Wolf, which changes de HUD and alot of helpful features -
http://www.nexusmods.com/witcher/mods/669/?. The mod is legit and the comments were all positive. But on downloading it, avast! told me it was infected with win32:malware-gen and locked it in the chest.

After searching on google, nobody has had this problem with the mod and some people have had infected files turn up to be false positive and completly safe.

What should i do? Should i put it in the exclusion list of scan and install the mod or forget about it?
