Alright I did a complete system recovery, and all should have been well. i installed avast again and after a few days the same infections came up, the only thing I did: watch youtube. nothing else. Scan after scan reveals more of the same, I dont know if they are fps, i submitted files to avast. boot time scans do nothing, but find one virus. I tried other fixes. should I just dowload another AV and see if it detects the viruses?
