Workaround for the 99% CPU Problem with the latest Virus DB Updates

[Guest]

Sure reinstall wil also fix the issue if you can do that.

In few hours ago, I re-installed the v3.12, but the problem exists.

At first, I use v3.11 and find cmdagent.exe problem. Then I uninstalled the v3.11 in SAFE MODE. And install the v3.12 in Normal Mode. After updating the Database, the cmdagent.exe problem appears again. And I need to Uninstalled the v3.12 again.

I have no antivirus software now, and using the WinXP default firewall only.

Is it possible that I install the v3.12 again, and place the v2456.cav into scanner directory directly without updating the Database?

Yes but you have to rename it to bases.cav otherwise it won't work.

I downloaded the database restarted computer and went in safe mode deleted the
problematic database and replaced it with the old database,restarted computer
and updated to a new anti virus database.
Everything went back to normal.

I have no problems whatsoever with CIS product and i will continue to use it.
Workaround was presented,developers and Melih have apologized and i except their apology.

Thank you very much.

Like most users of CIS.
I got the same problem when I was converting a flv file with Axx Vxxxo Converter.

At that time, I considered it was just a normal crash of converting the video or

there were some problems with the converter.

So, I reboot it!!

After the reboot to the desktop loading process, the God dang problem was still existing.

I thought that there were something seriously wrong.

Not a newbie of repairing the PC,

on the beginning, I thought the problem was that svchost.exe had been broken

because the CPU usage recover after I terminated one of the svchost.exe process which took the most

usage of memory.

After searching the svchost.exe data on the Internet, and reboot the computer many times.

The CPU usage had been still 100%, and I reexecute the process manager again(with very very slow speed).

Finally, I got that cmdagent.exe is the critical bug in the system.

I even don't know that the process is originated from CIS.

Search again, and come to this forum with Google's link.

Then,
I find that there are many users complaining the problem and said that uninstall the CIS is the
fastest way to fix it.

I think uninstallation is escaping the problem, and it won't be the winning for me.

So, after reading many articles, complains, and text data, I fix it in the end with the official workaround announcement.

Last but not the least,

It took me almost 5 hours to fix it. What about other ordinary users ??

I hope that before a new update announces, staff of CIS have to reexamine the program again strictly.

THX for reading this long-winded diary.

Regards.

Hi alec. I merged your post with this topic as it is about the same phenomenon.

The AV portion of CIS definetly needs more work if just a definition update can cause all this.

Or better yet, why wasn't this caught before "going live"?    

Edit: Just did the fix. Hasn't helped the massive disk I/O slog when the DB updates.

Well done! Three or more hours of my life are gone    


I have used the Vista´s restore point, so I have many things to repair 

[forum1]

I used your product 2,3 months. There were no problems. Simple and perfect. I was very pleased.
I installed it first on XP. Then on my second computer that has Win 7.
Again, I feel happy and secure. There were no problems.

Today was couplating DAY after your facking update. SORY amatures developers. I Launches my first computer and complete block. Run second computer. Too. After 5 hours lost and reinstal XP. Found that  Commodus is firewall block my OS. cmdagent.exe in taskmanager show 100% CPU usage.

 You are amateurs. Not only screwed up mycomputers. Well, I lost many time. Never use Komodo. .

It could very well be that because of all the trouble the update servers are busy....

JUST FOR TESTING please try to download this and see if the download works, after that delete the file...

I had installed CIS for a few of my friends' pc's and have had them call today reporting that they can't use their pc's, and since they aren't the most computer savvy people, I had to go and fix the problem (uninstall CIS in safe mode in this case, as there was no sureway fix at the time).

I got hit w/ the same influx of phone calls this morning and was not a happy camper.

I consult for a number of small businesses, and spent the better part of the day fixing this issue for people.  I couldn't even charge for it, b/c more often than not, I had recommended the product.

Ahwell.  It's not like Microsoft, Apple or even Ubuntu haven't released updates/patches that crashed a system from time to time.  No one's perfect.

Thanks for your trouble but Windows does not recognize this file so i am not able to open it.

If it is that the servers are busy then tomorrow will be OK with me.

I have to say I'm fairly shocked & appalled by the carelessness displayed here.

Absolutely. This is completely shameful. I am a consultant trying to meet a deadline and both OS'es on my computer were dead unresponsive. The mouse cursor would even stop tracking. Since two different versions of Windows had the problem, I spent 6 hours replacing hardware bit by bit. Finally I have the patience to wait 15 minutes for task manager to show up and there is cmdagent, completely paralyzing my system.

Rest assured this is my last Comodo experience.

That is why my pc freaked out today!I thought that I something messed up.. I Had to reinstall CIS
