Bug Reports for


Comodo Antivirus beta has been replaced by Comodo Antivirus beta. A big thank you to everyone who has helped with the beta testing (:CLP). Those who are interested in testing the latest version of Comodo Antivirus 2 beta can get more information on Comodo Antivirus HERE. You can also report bugs HERE.

Thank you everyone for your help!


  1. The on access scanner works with Hips (on it were incompatible at my system) but every 10 seconds locks the pc for another 15 seconds and so on. ???

  2. The submit process stops if a file to be submitted is not found. I have to uncheck them manually and retry the submit to make it continue.

  3. Although I have stoped the initial scan, Hips has scanned all my partitions :o. Why is that?
    I performed a scan only at the C:\ partition; but I see exes and dlls from my other partions ready to be transmitted (:AGY)

Can you pl send us(support@comodo.com)/upload here the troubleshoot log?

ok, This bug will be fixed in next release.

Is is possible that those files(exe and dlls) were queued for submission while CAVS Beta 2.0.01 was running and you had scanned all drives. This is possible if you choose not to delete user profiled safelist database while uninstalling the software. And hence the previous queued files which was not submitted will be present.

Hi Kishor,
No it is definetly a bug. It was a clean install. I used an image of my disk that I had made before installing the version

I upload the troubleshoot log for both version and .

My results with the CAVS Beta …

Three times I have uninstalled CAVS Beta, re-booted, and installed it again; but each and every time I have experienced the same outcome. And each time I have not been able to open the Comodo AntiVirus user interface, so I have not been able to view it or poke around in it, etc… On a positive note, the uninstallation process appears to work alright.

During each installation process I receive the error message: “Comodo AntiVirus License Activation Module has encountered a problem and needs to close. We are sorry for the inconvenience.” Once the message is dismissed, by choosing either the Send Error Report or Don’t Send, the CAVS installation continues.

After it’s “installation” finishes, I re-boot. Upon entering Windows, CAVS begins the process of creating it’s User’s Profiled Safelist database (UPSD): it checks 68200 files, and the number of files in its UPSD is 9694 files. It takes 6 minutes and 30 seconds to complete.

And while creating this UPSD the system is slow to respond, with lag times in responding to a previous mouse click or keyboard press. And the system pretty much remains unusable, with the same symptoms, even after the UPSD has completed; of course HIPS is still doing it’s own thing.

When I click on the Submit button of the Safelist file submission window (the only window which shows itself to me :-0) I receive the following error message, “Your Internet connection is not active. Please check your connection and try again.” (However I am indeed connected to the Internet.) So I click on the OK button of the error message dialogue box and click on the Submit button again, and it begins the submission of files. I go through this process each time the Safelist file submission window newly opens.

And speaking of the CAVS Safelist file submission window, could the Default width of column headings be adjusted so that on first run of this window it will also show the Progress column heading. This would be a help to the end user being able to know it is working, being able to see the progress it is making. Presently after pressing the Submit button all one immediately sees, without scrolling horizontally, is that the Submit button is greyed out.

I may yet take the plunge and try installing CAVS Beta for the fourth time, but if not then I will definitely download and install the next Beta release.

Looking forward to the next rendition of the CAVS Beta. All stability, speed, and performance improvements welcome. :slight_smile:


This system is running Windows XP Home SP2, all Windows Updates applied, a Pentium IV 3.4 GHz with 2 MB L2 Cache, 2 gigabytes of RAM, and a SATA II drive.

  • I often have the message “Le processus ne peut pas accéder au fichier car ce fichier est en cours d’utilisation par un autre processus.” when I add an application to the safelist database.

  • When I copy file (I use supercopier http://supercopier.sfxteam.org/), the copy takes 4-5 seconds to end.

  • Some applications freeze often for a few seconds.

CAVSubmit bugs:

  1. When its database is refreshed it blocks the pc for a few seconds. Probably because it uses all the CPU power.
  2. It’s impossibile to close it. I clicked exit for 5 times. It closes and reexecutes almost instantly.
  3. Twice it has frozen the pc. I had to do a cold reboot both times. The only common thing that I have done was to simple open a folder. 2 different folders in 2 different partinions. The first had only mpegs in it and the second was empty.

I have tried installing the latest beta on Windows 2003 Server and found with it installed the WINS service (WINS.EXE) uses 100% of the CPU. I also saw this with beta 1.1. In both cases the WINS service’s CPU utilization returns to normal once Comodo AV is uninstalled.

Hi Laurence,

Please give the IE version information installed in your system.

Hi Gopal,

I am using Internet Explorer 7 (Version 7.0.5730.11). You think there might be something related here eh…

I did not try a fourth install as I said that I might, but when the third release of the CAVS 2 Beta is available I’ll download it and see what happens.

Since the last Beta install I have done a little house cleaning on this machine, so perhaps it will successfully complete the CAVS installation (without error) the next time.

Thank you.



If you have four files in the file submission list (A, B, C and D) and, for some reason, B can’t be submitted, the submission process halts, rather than continuining on and submitting C and D.

Possible to make it skip the unsubmittable and continue on with those it can submit?

Not a big problem, but annoying.

Re. the intermittent 10-20 second hangs - I was able to monitor this today and the app that consumes 100% is CMAIN.EXE.

Hope this helps,
Ewen :slight_smile:


I have gone ahead and locked this topic since Comodo Antivirus has been released, thank you everyone who took time to test and report the bugs they found. I have edited my original post at the top and you can get more information on Comodo Antivirus beta in the links I have included in the first post in this topic.
