Is there a "Process, Block" script?

[Evil-e]

I have a couple silly GameTop "free to download, but please browse our website when you stop playing" games. So the browser is launched upon exit of game and currently using "Process, close, Chrome.exe" in script to crash the browser.

Hoping there is something that will stop Chrome from launching at all, rather than crashing it after the fact. I checked the Docs & searched posts and no luck

Thanks, peeps
