[Haskell-cafe] virus/trojan in bamse package?

hi, my Avira antivirus program says that there is a trojan in the bamse-0.9.5 package. I downloaded the hackage-torrent a week ago, and Avira says "TR/Crypt.CFI.Gen" is in bamse. To be sure, I downloaded bamse-0.9.5 from hackage today, and now avira says less specificly that there are "some viruses and/or unwanted programs" inside. Since I have some trojan trouble for a few days now, bamse might be the reason for that, but I am not sure. Maybe it is a false alarm, I can't determine this. (bamse is a framework for building Windows Installer, so it might contain code that looks like a virus or alike wrongly?) Does anybody know if this is really a virus/trojan? Best regards, Daniel
