Dear Hazelnut,
Chickened out on the safe mode, but interestingly I installed the program called unlocker like you suggested, and low and behold, the unlocker program popped up and said that the program Spybot was keeping it locked!! I instructed it to unlock, closed the program and then was able to delete it, fantastic!! thank you for all your help, its appreciated. I think i might leave ths program on my computer, it is a gem.
