High CPU usage

Comodo Internet Security - CIS Defense+ / Sandbox Help - CIS
#1

Hello all.

Windows 7 Pro x64
Core 2 Quad Q9550 [at] 3.4GHz
4GB DDR2 Ram
GTX460 1GB

I’m running CIS 5.3.176757.1236 with ONLY D+ and Firewall installed, no AV. I also have Microsoft Security Essentials installed, and use that as my antivirus as I have had poor experiences with Comodo’s AV previously.

MSE versions:
Security Essentials Version: 2.0.657.0
Antimalware Client Version: 3.0.8107.0
Engine Version: 1.1.6502.0
Antivirus definition: 1.97.1582.0
Antispyware definition: 1.97.1582.0
Network Inspection System Engine Version: 2.0.5854.0
Network Inspection System Definition Version: 9.1.0.0

Sometimes I notice my CPU usage spikes up to 25% (quad core) and the culprit is cfp.exe.

I game quite a lot and when cfp eats my first core like that, ANY game running bogs down and becomes unplayable. It only happens for short bursts, but it should not be happening in the first place.

cfp also eats 25% CPU when I run my weekly virus scan with MSE, so I think it is getting caught up trying to check all the file reads by MSE.

Hell, as I write this, cfp is using CPU:

1024×640 89 KB

I have checked for remnants of old antiviruses (AVG9) and can find nothing. I do not have Sandbox enabled. I have tried running in game mode, that picture I took was in game mode. I have a trial of NetLimiter 3 running in the background, as well as FRAPS, Steam, XFire, and MSI Afterburner.

Halp?

EDIT: I also mainly leave D+ and the firewall in training mode so I don’t have endless popups.

Bump.

Hey and warm welcome to comodo forums Biltong! :slight_smile:

Add MSE here (CIS —> Defense+ —> Defense+ Settings —> Execution control Settings —> Detect shellcode injections (i.e. Buffer overflow protection) —> Exclusions —> Add —> Browse…)

Could you also provide us a screenshot of your defense+ logs

Thanks! :slight_smile:

I’ve added MSE to the exceptions. I will see if it makes a difference.
My Defense+ logs are quite empty, just some stuff about steam accessing the memory of comodo and Visual studio express changing a temp file.

if you’re a programmer then I suggest you follow these steps.

1) CIS → Defense+ → Computer Security Policy → Protected Files and Folders → Groups → Add → New Group…(give this group a name). Now click once on “add files here” and Add then Add → Select Fromand → Browse… and add find the wanted folder

  1. Defense+ → Computer Security Policy → Defense+ Rules → Add → File Group and then choose Installer or Updater

Execute 3) only if 1) and 2) won’t help.

3) Add the created folder here CIS —> Defense+ —> Defense+ Settings —> Execution control Settings —> Detect shellcode injections (i.e. Buffer overflow protection) —> Exclusions —> Add —> Browse…
