That is what I suspected as it would be no different to your trying to delete, which is why I said ‘even if you were able to’ Given the error message The system cannot find this file.

I believe this to be an issue effecting a small number of users (why only a small number is beyond me) as in all the tests I have done with various scans over XP and win7 I can’t replicate it. There are a few other topic in the forum relating to these PID detections and so far we haven’t been able to pin down the cause, but I don’t think you have anything to worry about given that when trying to deal with them you get the message ‘The system cannot find this file.’

Use the avastUI, Maintenance, Update section and ensure you have the latest avast version, 6.0.1289 and the latest Virus Definitions (VPS) version, currently 111027-0 and update if required.
