PostUpdate.exe/Windows
If anyone else is plagued by this (?possibly dodgy?) activity which sits in the sys tray and cannot be easily removed, the only way I have found is via 'Hijackthis' in the 04 block. Probably a shockwave update file, but known also sometimes to be an 'infection cover' depending on file size and name. Mine sat in the Macromedia folder, but did not show in the reg in 'Run' or 'Run Once', nor in start-up and just would NOT go away!
