Macuser22, thanks for your responses. I am not tech savvy enough to be able to figure out if my primary user account is corrupted and if anti virus software is causing it. I also didn't have any luck trying to remove TT21 software and the hidden library files. As I had reported, it made matters far worse by corrupting the software that had been working so that I had to recreate a 3rd user admin account. Very possibly I didn't remove all the files, since someone reported that not all of the files are in the hidden library folder.
Do you know where I could go to get professional tech support to help with this kind of issue? I'm thinking of visiting the Apple store, but they will probably say this is a TT issue.
