System process High CPU Usage with CPF turned On

Sometimes I get 100% cpu usage for no reason when on my computer.

It appears to be caused by Comodo Firewall

The system process consumes as much CPU time as possible, and CPF.exe also uses more than usual

I have used process explorer to find that there’s nothing listed under system process using CPU, it’s the system process itself. (see attached screenshot)

If I turn Comodo Firewall OFF the CPU usage goes to normal. Same also happens if I unplug the ethernet cable going to my ADSL router.

Also, if I wait long enough, the problem fixes itself after maybe 10 - 15 minutes.

I can’t see any relation to what I’m doing and what causes the high CPU usage.

I don’t know if you are still waiting for answers, but I don’t have any!
In fact, I have the same problem as yours (cpf.exe uses about 95 to 100% CPU), except that in my case, the problem doesn’t stop after 10 or 15mn… which is quite embarrassing! I also use Avast!, maybe the combination is problematic?
So, if anyone have a idea…! Wellcome!

Let me open the good book from my signature:

[b]Version 2.4 - cpf.exe and High CPU[/b],6819.0.html,6933.0.html,6943.0.html

As for the system process hogging cpu, my only suggestion is to reinstall CFP (delete all cfp registry keys afer uninstalling) in safe mode.

In your screenshot, CPF only appears to be using 4.69% of resources, so I don’t think that’s likely to be the culprit.

What the likely cause is, is the amount of applications you’ve configured to run on startup. For example, do you really need this one running all the time? And what about this one, or this one? You can run all these manually any time you wish, but running them all the time regardless is going to deplete your system resources.

Check the rest of the apps loading on startup on the same site and then disable those which you don’t need running all the time by unchecking them in MSCONFIG → Startup (tab).
