BSOD Last Known Good Configuration or Safe Mode Uninstall?

Compaq 5441 Rebuild:

I've been rebuilding a friend's OLD computer after a hard drive crash (Compaq Presario 5441, Win2K professional, GA-5SMM motherboard, 512MB SDRAM, AMD K6-2 475 MHz, 40 GB WD HDD, integrated video and sound). To make this doorstop useful, I had to find an Antivirus program that would work in Win2K. A six-month old version of AVAST worked (evidently AVAST no longer support Win2K). I had to apply several updates to Win2K and a hotfix before AVAST would install. After AVAST installed the definition updates were not downloading. I changed the settings in AVAST to "this system is always connected to the internet." The definition updates would not download after the settings changed so I thought a reboot was in order.

After restart was selected, "BSOD."

I receive the following, ""systemroot\system32\drivers\aswSP.sys device driver could not locate the entry point SeTokenObjectType in driver ntoskrnl.exe"

I am wondering whether to try a potentially messy uninstall of AVAST in Safe Mode using pcdecrapifier or last known good configuration?

NOTE: aswSP.sys is associated with AVAST.

I installed quite a few updates and some other programs and I did not note the installation order, or note if or when a restore point was created. I fear selecting "last known good configuration" upon restart may be an equally messy alternative.

I do not suspect a root-kit virus but this is a remote possibility. I cannot boot normally so attaching logs would not be very helpful.

Can someone assist me with potential alternatives? The obvious is not desired, "an in place repair of Win2K."
