Kinda suprised safe mode doesnt work. I think it might have to do with mcafee. Can you boot into safe mode with command prompt and try renaming the mcafee folder? You would have to navigate to mcafee folder...if that is too much and you have another computer you can burn a cd with would just burn a copy of knoppix and boot into that and go into your hard drive and rename the mcafee folder or if you are pissed off and dont want to deal with mcafee anymore just delete it. Be warned you probably wont be able to uninstall it successfully if you delete the folder.
If you want specific help doing that I can give you a list of commands to run to get to that folder so you can rename it.
