Thanks. I deleted the task. Here's a screen shot on mine for the same screen you attached. I can't seem to generate that same screen you have for me to change my settings. I think what happened was that I was prompted to delete after my scan and accepted it with haste not knowing or realizing what was being deleted. I was thinking it was just like a windows disk cleanup. It should not have included those files to begin with... those are files within "my documents" folder and it does not have any business snooping around within that folder. Wouldn't you agree?
the QuickClean only deletes files in the Temporary Internet Files folder, Recycle Bin, Outlook Sent items, Outlook Recycle Bin, etc. It won't delete files/folders in My Documents unless specified by the user (using the McAfee Shredder).
also, in order to get to the screen (Ex_Brit's screenshot), you must click on Maintain Computer on the left hand part.
