Have you tried an offline scan of the machine?
-Stoic Joker
All of the above mentioned full scans were offline.
I presume you are suggesting that Kaspersky may find viruses or malware that Avast, SAS, MBAM cannot?
+1! If Kapersky's offline scanner can't find or fix it, it's either not there - or it's not repairable and you'll need an OS restore to get around it.

I am somewhat reluctant to invest in another AV program. I may just download the Avast rescue disk to flash and run that.**
If I choose this Avast option... how should it be done? Just leave it plugged into a USB port and restart?
**Foolishly I bought an Avast rescue disk, a while back and it even has my name on it. Whoop-de-do. Now it appears that CD is basically useless
because the virus definitions are outdated. But now it seems I can create an up-to-date rescue CD or flash from within the Avast GUI.
Do people still hang CD's from their rear-view mirrors?
