Hello the Beta Team, How are you? MBAR tell me that I have a pest which is quarantined. But, this stuff is NOT quarantined it still exist in the original folder. Where is the quarantine? Just to look at. In fact, this is TIWORKER.EXE from the folder winSxS. As I can read on the net, this folder is very important (win 8.1). But I also read that Tiworker was, very often, the target of hackers. Then, I don't know if have to report this entry as false positive. Or what to do with it: delete or not delete, that is the question. (fortunatly Shakespeare didn't have a computer). So I hope to sleep this night thinking about you working Regards
