This has probably been covered before but bare with me. Temporary files wizard skips these files JET7290.tmp, JETF0DA.tmp and ~DF165A.tmp and will not delete them. I'm almost sure they belong to one of the Acronis apps. Does anyone know what they are? Some research suggests the JETs are keystroke loggers. In addition there are quite a few files skipped (and unidentified) in prefetch, any clues?
