Had message from AVG saying incorrect file above checksum (CRC) the file is probably password, so successfully removed from my computer. Seem to be having trouble with MSG Plus Live, don't know how I got it, I did remove the Plus Live program, although Live Messenger is still there. Would it be a good idea to remove Messenger completely and start again or would that bring its problems? I did google the file and it seemed that the file was perfectly okay, can anyone explain. Many thanks for any advice once again.
