a friend was using my external drive on their computer and Avast detected a threat, so they disconnected immediately.
I scanned the drive on my computer using malwarebytes, avg 9 and superantispyware, didnt find anything
Downloaded Avast, scanned & found
N:\System Volume Information|_restore(2846F638-C5AC-45B1-8F7F-98C3A36B3599)\RP67\A0066582.inf
Error: The system cannot find the file specified (2)
Can not move, delete etc
Not very tech savy, suggestions on how to deal with this please! Thanks!
