Anything else?

This is what you should run in ChocolateyUninstall.ps1 to correctly uninstall it:

& "$ENV:ProgramFiles\Malwarebytes\Anti-Malware\mbuns.exe" -nosurvey -uninstall -silent

Alright so on this, even if you run this command to uninstall it, it will still pop-up with a "Uninstall Malwarebytes" screen with "Repair" or "Remove". Oddly enough, if you just close out of the window, it will still uninstall in about a minute. So that's what I did with this PR #227.

[pauby]

Thanks for the issue and the PR. I've fixed this in 9906cda

I took a different route from your PR and used the default chocolateyUninstall.ps1 script and added a .skipAutoUninstaller file to stop Chocolatey Automatic Uninstaller from trying to uninstall it (as it's already been uninstalled at that point).

Alright so on this, even if you run this command to uninstall it, it will still pop-up with a "Uninstall Malwarebytes" screen with "Repair" or "Remove".

I didn't see that in my testing - it just removed it as expected.

[asheroto]

So the reason I have the window closing in the script is because it will just stay open when uninstalling. Does it not do that now?

[pauby]

I tested it here and the window did not open. It's possible it does that under certain conditions and I didn't meet them.

[asheroto]

I tested it on Windows Sandbox and found that the screen sticks still on uninstall.

[asheroto]

Nevermind! Sorry about that, jumped the gun!

The latest version works for install/uninstall. Good deal. :-)

Thanks for checking on this.
