Is there a DOS command that detects if a program has started?

I'm attempting to perfect a program that automatically closes Internet Explorer whenever it opens. This isn't for harmful use, don't worry. I use Mozilla Firefox, and get sick of spyware that I can't seem to delete opening up Internet Explorer.

Anyway, so far I have this:

Code: [Select]ECHO OFF
:start
tskill iexplore
ping localhost -n 5 >nul
CLS
ping localhost -n 10 >nul
GOTO start

As you can see, it has to work fairly frequently to be effective. If anyone has a code that detects when a program initiates, please post it here.

Many thanks,

-Jake

Note: Not sure if this makes a difference, but I have this set up so that it doesn't open a visible window while its running. I'm thinking something along the lines of using the "IF" command to detect if Internet Explorer is running, and then terminating it.

So how can I make it look for the iexplore.exe process? Use tasklist

If you need more specific help, I'll give it later. But I'm at school right now.
