You can execute the task periodically using a timer (see Timer Class (System.Timers) | Microsoft Docs[^]) but... Are you really sure you need it?

The sample code, in the linked page, shows you how to set up a timer that periodically calls the handler.

First things first: if you are relying on "windows titles" to identify "rogue processes" then you are in for a massive shock: Titles can be changed at will, and it would be very naive to assume that all rogue programs will contain the word "Spy" in a window title.

Secondly ... a process doesn't have to have a window at all - there are a huge number of processes within windows that have no main window, and thus no Title, and are undetectable by your code.

Thirdly ... Just looking for any three letters in any kind of process info isn't going to help you much - it's horribly likely to cause "false positives" and close innocent processes.

Fourthly ... you can't kill any process - it may be running under a different user, you may not have the required permissions, ...

And finally: the problem you have noticed. We can't help without being able to see what happened when you try - we have no idea how you are calling that code, and that's likely to be important to the whole operation. I'd strongly suggest using the debugger to find out exactly what happens the second time that code is executed, and what has changed since the first run.
Sorry, but we can;t do that for you - time for you to learn a new (and very, very useful) skill: debugging!
