Comodo Updating Agent is slowing my computer


my free comodo internet security’s updating agent is slowing down my computer. this problem gets really irritating if it happens while i’m watching something. just now i tried posting this complaint using the official complaint format but for some reason i got an error, informing that the size of screen shot i attached is too large. please resolve this complaint


From the information you have given I am not clear whether this is a bug/issue.

For the moment I will transfer you to help so you can work through this issue with users and mods in this forum and hopefully resolve it. I hope that is OK.

This link may help you: here.

Please ask any mod to move this report back to the bugs forum if it becomes clear that it is a bug/issue.

Is the activity caused by the AV updating or caused by something else? Can you show a screenshot of your D+ logs?

thanks for replying and being helpful. please find the attached screen shot, you can also see comodo updating agent in windows task manager. cpu usage keeps fluctuating to 100 or somewhere in that region, but in the screen shot it is very low. and cmd updating agent isn’t coming up in the task bar.

Just to be certain; you have the AV enabled. Correct.

Can you keep an eye on when the problem happens and see if CIS is updating the AV? That can be seen in the main screen behind "The virus database has been updated on: ".

Thanks for the screenshot but that is from the Active Processes list. The logs can be found under View Defense + Events. Can you post a screenshot of them that logs the time your system slowed down.

Can you tell us what hardware you are using (CPU and amount of RAM) and what OS you are on?

please note, comodo anti virus and defence+ is not activated. win xp sp2, core 2 duo, 2 gb ram. comodo configuration is set at comodo firewall security. problem happens randomly and every time on windows start up. avast is enabled. i’ll post the defense + events as soon as i can.

i’ve seen the one you asked and it only contains list program names it has scanned. is that the one i’m being asked to post here?

That’s the logs I am looking for.

here is the screen shot. defence + is disabled in my system.

Best thing to do to make sure that there are no left overs of previously uninstalled security programs around. Not all uninstallers do a proper job. And left over applications, drivers or services can cause all sort of “interesting effects”.

Try using removal tools for those programs. Here is a list of removal tools for common av programs: ESET Knowledgebase .

i’m really sorry to say that i have uninstalled comodo cis free. i’m using zone alarm free now. the problem has gone but even with zone alarm it is reaching 100 percent after few minutes if i connect lan cable directly at the back of my cpu, but it doesn’t happen like this if i connect through router. i’m guessing this was happening because of some stupidly configured lan by my cable operator or some virus on their network.

i wish comodo success and prosperity, for whatever few years i used comodo products it had been great, although i never used your paid product, but free ones were also some of the best. i willl even switch back to comodo when a new version comes out which isn’t plagued by this problem or after i figure out how the network was causing this problem.

thanks a lot for your efforts to help me. writing this post has been one of the hardest in my cyber life.

Sorry to see you go.

Still I strongly suggest you to run the clean up tools. That’s a way of knowing there is a clean slate to work from when it comes to possible interferences of other security programs.

Also add the Comodo or Zone Alarm installation folders to the Exlclusions of Avast AV and see if that makes a difference.

When connecting through the router the high CPU usage goes with both CIS and ZA there may be an external factor playing a role. Can you confirm that the router clones the MAC address of the LAN connector of your computer?

my router is dlink di-524. it has some ability to clone mac address but i think it is only limited dhcp. i spoke with the network operator, he said that if i have a firewall i won’t be able to browse, when i asked why, he wasn’t giving an answer. maybe he suspected i would have a bad configured firewall.

The network operator representative was not very helpful. I agree firewalls can be a problem but their influence can be easily determined by temporarily disabling it.

And now a completely different angle. Let Windows check the file system integrity as described in this Microsoft KB article.

Also make sure the IDE channel of your motherboard is in UDMA 5 or UDMA 6 transer mode like it should be. Read about it here: .

i’m back to comodo free cis. but now the problem is when updater agent shows up in taskbar, it doesn’t open up when i double click when my pc is connected to internet. but the updater agent opens up when i double click it when my pc is not connected to the internet. can this be resolved, how can i update cis if i can’t click it and open it up?

When CIS checks for program updates (and also whitelist updates) it will show a second shield icon in the systray for up to 5 seconds or so. Don’t click on it unless you see a balloon message saying there is an update. That’s all there is to it. It is confusing though.

ohh…thanks. i thought i had to double click it and download and install the updates. anyway comodo products are great!
