Hello, I ran a full scan today and it said there is one threat located in my Steam games folder, specifically in the game folder for Audiosurf. And the file it found said it was a "Trojan.Agent.rf" which was found in the engine folder, and the file called "QuestViewer.exe". After this was found, I deleted the file and restarted as Malwarebytes requested, scanned again and was fine. I then did a system restore to about five days ago, ran another full scan, and the same file came up with the same threat definition. Can someone confirm if this is a false positive? Thanks in advance.
