I apologise if this has been answered before. I have Vista Home Premiumn 64 bit. If I try to empty my Delete Folder the files all vanish except for a single file,of which 50 identical copies remain which then proceed to replicate itself indefinitely so I end up with thousands of this file in the folder,literally. The file itself seems to be unimportant-a notification .html-but I just can't stop the process. I did once manage to get rid of them all but when I rebooted they were all there again. I tried the MS K941090 update which has been suggested but am told my system doesn't need it. I jus can't empty my Delete Folder. Please can anybody help?
