Spybot won't uninstall on new Win10 notebook

[attrakk452]

Hi... I bought a new notebook loaded with Windows 10 a few months ago. Last week I got hit by malware, and ran Malwarebytes, Spybot and a couple AV programs booted from USB sticks which seem to have resolved the issue.

Malwarebytes uninstalled with no problems. But after uninstalling Spybot, I keep getting a Spybot popup after booting Win10 that says:

"Welcome to spybot Re: installation"

Searching the forums here I found several posts where the resolution was to: "Delete the file 'Post Windows 10 Spybot-install' from your desktop", or from the \ProgramData folder for Spybot.

However I have found no such file even after searching the entire C:\ drive.

Looking at Win10's MSCONFIG which is now a 'Startup' tab in Task Manager, I see where the Spybot re-installation program is set to start at boot from residual files that the Spybot uninstaller did not remove. I've disabled Spybot there, which at least prevents the Spybot re-installation popup at boot.

So... What do I need to do to at this point to complately remove any last vestiges of Spybot from my system now?

Thanks in advance for any help on this.
