Troubleshooting ways to counteract a forkbomb scripted in batch

[treneth333]

@echo off
:Start
Echo %0|%0
Goto start

This scrip will cause the central processing unit to try and process a continually growing process tree

If the program is allowed to run long enough the system will completely freeze, requiring it to be forced to shutdown.

My idea is making a program that monitors the cpu usage for every process and if a process tree ends up taking more than 80% the entire tree is halted.

I guess it's like active security compared to an antivirus software that's usually passive.

Any ideas for an active security program?
