Originals of deleted/renamed files persist, like zombies

Bump! I can't believe nobody else is having this problem?

===================
I have a number of files I have deleted or renamed but the originals
all come back after restarting Windows. I'm using Vista Home Basic,
have UAC turned off and always run as Administrator. (I have off-line
drive images and critical file backups). I've Googled the problem to
death but not found this problem described elsewhere.

Any suggestions?
