I wanted to say to @Darvond.

I worked with Avira support and they fixed the false positive for GOG Galaxy. All it took was for someone to report it. Their support contacted me, asked me to run a detailed diagnostic, and now Avira doesn't go crazy when GOG is downloading files.

Sorry for opening an old thread with the one I had commented on previously, but I felt it'd be nice for people to know what the issue was since nobody ever found the cause. Google led me to the thread.

And now, I can say it's resolved. Thanks,

If I were to say that most antivirus programs these days are thinly disguised malware clients, would that make any sense?
