Can't update CIS antivirus database [Issue Report]

I can’t update CIS antivirus database.
When I try it, after a while, I get this errro message in Spanish:
Error al actualizar la base de datos de virus.
Por favor verifique su conexión a internet e inténtelo más tarde.
I did some research in the web and I found that perhaps I should run Comodo with administrative privileges, but I was unable to do it. I got more error messages:
No se puede iniciar el servicio, porque está deshabilitado o porque no tiene los dispositivos habilitados asociados a él.
How could I update the virus database?

Reinstalling it solved the problem this time. Thanks.

The bug/issue

  1. What you did: Tried to update the virus data base by clicking in “Update Virus Database” or the “Update now” button.
  2. What actually happened or you actually saw: Error message saying something like “Update the virus database failed. Please check your Internet connection and try it later” (but in Spanish).
  3. What you expected to happen or see: "A progress bar filling while downloading and updating the virus database. Then a message box saying “Done. The virus signature databas is up-to-date.”.
  4. How you tried to fix it & what happened: I tryed to run Comodo as administrator after closing all instances of it. I couldn’t.
  5. If its an application compatibility problem have you tried the application fixes here?: I don’t know about compatibility. It worked before. I haven’t made mayor changes.
  6. Details & exact version of any application (execpt CIS) involved with download link: Not applicable. It’s a Comodo issue.
  7. Whether you can make the problem happen again, and if so exact steps to make it happen: Yes. I still can’t update CIS in this, the normal way, nor in another one.
  8. Any other information (eg your guess regarding the cause, with reasons):

Files appended. (Please zip unless screenshots).

  1. Screenshots illustrating the bug:
  2. Screenshots of related CIS event logs and the Defense+ Active Processes List:
  3. A CIS config report or file.
  4. Crash or freeze dump file: Not applicable.

Your set-up

  1. CIS version, AV database version & configuration used: 5.4.189822.1355, 8482, “Comodo Internet Security” config (grayed).

  2. a) Have you updated (without uninstall) from CIS 3 or 4: Yes
    b) if so, have you tried reinstalling (if not please do)?: Yes. This solved the problem this time. I didn’t reinstall it before to post first. I should install it twice to get the antivirus. I thought the download page isn’t clear enough to be fool’s proof and I downloaded the firewall only version, without antivirus. It happened to me many times that I download the FW+AV version and when I install it the Antivirus section in the interfase is gone. I uninstalled Comodo and installed it from scratch from the same file that I downloaded (cfw_installer.exe), and the antivirus is back, and the update is working. I’d wish to not have to do it all this again. I have another antivirus installed, (things like this make me think that I really need it), but I think that an antivirus without firewall is as incomplete as a firewall without antivirus.

  3. a) Have you imported a config from a previous version of CIS: N.
    b) if so, have U tried a preset config (if not please do)?: Yes

  4. Ave you made any other major changes to the default config (eg ticked ‘block all unknown requests’, other egs here.): No

  5. Defense+, Sandbox, Firewall & AV security level: D+=Safe, Sandbox=Enabled, Firewall=Safe, AV=Stateful

  6. OS version, service pack, number of bits, UAC setting, & account type: Windows XP, SP3, 32 bit, None in XP, user account.

  7. Other security and utility software installed: CAS

  8. Virtual machine used: None.
