On another forum where I am registered, a poster has a problem with Perflib and Perfdata. He is trying to delete them but they keep coming back. I tried to tell him that they were created by the Performance Monitor and were an essential part of the OS and could not be deleted. The Admin of the site suggested that he turn it off through the Process Manager. Didn't work. Another member of the Staff said she had tried and couldn't keep it away. Another 3000+ poster said he thought it was created by DiskKeeper. Have I lost it, or have they?
