Thanks guys so much! I haven't gotten to it yet, but here's what I'm going to do:

1. Scan the computer and make a note of each infected file.


2. Research what that file is for and how necessary to the operation of the computer.


3. Find 'clean' copies of those files crucial and necessary to the computer operation.


4. Go into the system directory and replace those infected files with the clean ones.

Does that sound like a plan?
