I play a game called tibia and every time their is a client update avast flags it as malware, its picking it up as filerepmalware.
oddly enough virus total scan shows its clean, but when i opened the program, avast just killed it,( i didn’t see exactly what avast did since I launched the game and walked away to go to the bathroom, when i came back it was in the vault.)
I have played this game for a over 12 years, its only been the last year or so, that when ever a major game update hits and it requires a client update, avast flags it.
