Disk Cleanup (every option), Disk Defragmenter.
Then I ran a variety of programs I'd heard of, including:
Also some programs from GMER relating to rootkits, but I'm not sure that I had one of those in the first place.
Each identified a number of viruses and or other problems with the computer and fixed them.
Afterwards, however, there were a number of problems. First off, the CD drive was no longer recognized. (The driver was corrupted). After a deal of searching I found a Microsoft "Let Us Fix It" which made the drive appear again. However, now we have other problems.
Although the drive is visible, CDs put into it aren't working properly. We can open the CD via My Computer (and all the files are there), but none of the programs are working. Also, once we have opened the CD and tried to run something, the computer almost freezes up. I can't open task manager (altho the system resources icon appears in the system tray), etc.
As a separate issue, I can no longer right click on any of the programs in my start menu (under all programs). The list merely flashes, and no menu appears from the right click.
I'm running XP SP3 on a rather old computer. If there's any additional information you would like or logs you'd like me to post, let me know. I'm not going to be running any other antiviral programs without being asked to here . Thank you muchly for your help.
