I have a very annoying problem where a set of around 40 .exe files will not delete. I think this may of came from when i downloaded a file from a p2p network. The files keep on appearing in folders, then once i delete them they will re-appear in another folder. They files all seem to be 'crack' files for computer games and other software. When i enter the folder with the files, the whole computer seems to slow down. I have used AVG anti-virus to scan the computer but it picks up nothing. Also scanned the computer using ad-aware.
