My Symantec antivirus detected an instance of the W32.Spybot.UBH on my
machine, however, it could only quarantine it, not delete it altogether. I
have been following the instructions on Symantec' website
which, at one point, require deleting

Unfortunately, RegEdit just won't allow me. When I locate the key, and press
delete, I get an 'Error Deleting Key' popup message. Any suggestion? As
always, thank you in advance for your ideas.
