ptsnoop.exe

hi, hopefully someone can help. i have an executable file loading named ‘ptsnoop.exe upon start up of the pc. I have removed it through ‘msconfig’, i have also removed it from the registry and it keeps coming back. When you search for the file through start/find/files or folders nothing is found. I’m running windows 98se and desperately want it off my pc. Any help is appreciated. Cheer’s. J.
