Nothing I can find gives it bad press OR say there could be problems with it and it IS highly recommended by one of our own, PP, in his thread here. I also can find no information whatsoever about the supposed file. Have you looked in the temp file to see if it is there? If it is a temp file it CAN be deleted.
If I were you I would do some other scans and see if other programs pick up the same thing. Use the steps here
and see what, if anything, turns up. Use at least a couple of the online scans, one being Kaspersky. You cannot remove with Kaspersky but it will give you a list of problems if found. Post it all back here.
