Hello,
I opened Humble Bundle website, Satisfactory game page, and Avast immediately threw this report. I believe it is false positive caused by some AD that appeared on that website at that time. Problematic file seems to be firefox.exe
I once had similiar problem happen to me, but on Train Sim Bundle or something like that, and too on Humble Bundle, few months ago.
Can you loot at it please? I am very certain it is false positive, but just to be safe. Thanks
