Hi During a regular scan last night, AVG detected the above spyware within msmsgsin.exe in the messenger folder. The above file was then scanned with AdAware, A Squared, Outpost's Anti-Spyware and NOD, they all said the file is clean. But to be on the safe side, I deleted the file and did a system scan using AVG. It came back clean. I then copied the same msmsgsin.exe file from another PC which AVG said is clean back to the messenger folder, thinking everything is now OK, but as soon as I scan the folder using AVG, the alert comes on saying Trojen.KillAV have been detected... What should I do, at the moment, I have put the file in the exception list in AVG, but I don't think it's the best way to go about it!!
