I appreciate your helpful replies. Sorry I am slow to accomplish your suggestions.
Dr.Web® LiveCD Emergency System Recovery Disk was able to access the PC and run scans, however Avira AntiVir Rescue System was only able to begin loading, but the actual program never came up.
Several strange things are showing up:
Documents and Settings are show to be drive D, not Drive C:
Drive F appears to be another partition on the hard drive.
I am not seeing any files from the regular user account I normally use.
There are many read errors.
There should be over 1 million files on the PC, less than 100,000 were scanned
I ran Dr.Web once and found 3 infections; I am running it a second time.

My conclusion is the hard drive is failing. When the scan completes I will run a hard drive diagnostic, which will take several hours.
Again, any comments about my issues are appreciated.
Thanks
