Problems with the 3/24 release of the free Comodo Anti-Virus and Firewall.

I was using the x64-compatible version on WinXPx64sp2.
-- It has a bug that
-- Causes 100% CPU utilization after it loads on Start-up. This slows everything else (processes and programs) and drove my CPU temp from the normal 35C to 52-57C.
-- Comodo's processes in Task Manager are:
....-- cfp.exe and
....--cmdagent, neither could be stopped or ended in task manager.
-- The tray applet will not allow user to Exit Comodo (an option in right-click).
-- Comodo cannot be uninstalled in normal or safe mode using the Add/Remove Programs in Control Panel.

My solution was to install the trial version of Tune-Up Utilities and disable Comodo's startup in the TU shell>Increase performance>TuneUp StartUp Manager.

After re-start I was able to uninstall Comodo using Control Panel>Add/Remove Programs.

This is really a shame. I had been using Comodo for two years and was quite satisfied with its performance, learning mode, and threatcast community advice on allowing/disallowing programs' internet access.

Comodo's earlier version is still behaving normally WinXPx64sp3

You have something else, or it could be Comodo was hitting a lot of attackers. I use Comodo Firewall and never have that problem. Anyway, their A-V isn't the best, so test your computer for malware, using MBAM and SAS, then reinstall just the firewall and get Avast or Avira for the A-V.

Thanks area51. I'm using PC Tools for the firewall and AVG 8.5. I klnow 9.0 is out, but I can shut 8.5 down. I don't game on line, so I just shut the modem down and turn-off av and firewalls.

graywolf - There was nothing else running, and after I shut comodo down, my cpu usage went back to normal. It only happened with the latest free version (with the red skin), that's why I posted - in case someone else had it happen to them. OK, most people just post, instead if searching THFs for an already-solved problem.

I've been using comcodo for a long time, and I liked it.

I guess it just doesn't play well with something you have. :cry:  Many companies play around with software that ain't broke until they break it. Ditto AVG, which has become so bloated.

BTW-not being able to shut off Comodo temporarily is normal. They did that for protection. It has to be stopped in Services.

How do you choose best answer? Am I missing something in the Firefox interface?

It looks like THF remembers the original thread-starter and puts a box, labeled "Select as the Best Answer" above the box for each respondent post. I never asked a question, even with this thread - was just trying to allow easier search of the thread for comodo issues.

Thanks, treefrog. I'm sure I'll be asking questions, as I do at every forum.
