Query: Buggy!

Program will not install, either as an upgrade to 2005 or on a newly-cleaned system. Hangs, cannot be removed. Computer is in an indeterminate state now. I have been a professional programmer for 20 years and a PC user for longer than that. Symantec should be ashamed for releasing this trash on an unsuspecting public.
