How to write an unkillable process for Windows?

Question

I\'m looking for a way to write an application. I use Visual C++ 6.0.

I need to prevent the user from closing this process via task manager.

Answer 1

What I've learned from malware:

• Create a process that spawns a dozen of itself
• Each time you detect that one is missing (it was killed) spawn a dozen more.
• Each one should be a unique process name so that a batch process could not easily kill all of them by name
• Sequentially close and restart some of the processes to keep the pids changing which would also prevent a batch kill
