Half installed Nod32 4.0.424, how to fix?

I rolled out 150 installs of Nod32 4.x over the last 6 months. This weekend I installed about 450 more using Zenworks. I removed version 3, rebooted, then installed version 4.

About 20 PCs didn't install correctly. Nod32 is installed, but the registry keys are not there. EKRN has a lock on the registry so I can't change/fix those values. I can't add/remove Nod32 because it's not listed. I can't disable the Nod32 service as I get accessed denied as a domain admin.

What's the fix here?

 

I used killbox to kill and then replace ekrn.exe on reboot. Rebooted twice and removed the registry entries.

 

While Killbox would probably work, I found something else that is easy.

I've had about a dozen PC's where Nod32 fails to install correctly, will not uninstall, and is left broken.

Step #1 is login as admin and configure in advanced settings to disable "Enable self defense"
Step #2 you must reboot
Step #3 reinstall Nod32
Step #4 go into settings and Start Realtime Protection
Step #5 Go back into advanced settings and re enable self defense and reboot.
