Oh dear... none of this should happen...
It looks like another messed up Norton installation, I sometimes get the impression that Norton causes more problems than all the malware put together, the number of people that can't connect to the internet, or specific sites,and Norton turns out to be the culprit, runs into thousands, and when you try to uninstall Norton, more problems start, nothing is easy with Norton... you are definitely better off without it.
will you check this please...
Delete the files from the NPROTECT folder, then look in your recycle bin ... are they in there ?
empty your recycle bin, then check the NPROTECT folder folder again...
Are they just moving backwards and forwards from one to the other ?
