Thanks to you guys who replied with a wealth of advice and information. I
appreciate that and the patience you have taken.

There is a lot to work through but so far, in addition to what I already
listed, I did the things that were suggested in the Symantec site (re: safe
mode virus scanning, registry entry purging, etc.). I also ran the Panda
and Micro Trend online scans, safe mode virus scanning, system restore
purging and turning back on, deleting temp files, and checking the
downloaded applications folder. I also checked the running services and if
I could not identify something, I googled it to see what it was. Everything
was clean with no infected files and no bad services. I am leaning towards
believing that I had initially wiped it out and the latest Symantec
definitions caught an orphan. I was able to find a list of what was in the
Symantec definitions that were downloaded on 10/19 and there was a piece
that looked for the SVKP.sys file. Since I am not having any other slow
downs and issues, I think I have it beat. I will get to Mr. Lipman's advice
this weekend.

Thanks again.
