Thanks Rusty, I will check that.  There are still issues, but at least 
the computer is functional and Brad is able to conduct his business. 

Jim gave an analysis of the HiJackThis log I had, with detailed 
instructions on what I can do to clean up that computer.  Between Brad's 
schedule and mine, I have not yet taken care of that little chore.

Thanks for checking up on me.  I do appreciate it.
