Is anyone else experiencing problems with automatic signature updates? After my April 30 post I was finally able to get my updates working again, but then beginning around 3:00 AM (CST) began getting the 0x80072ee2 errors and haven’t been able to update the virus signatures since then. Now I am getting a warning from Window Security Manager that Comodo is out of date. When I downloaded the latest bases.cav file from the database download page and tried installing the signatures I get another error “There is a bad version number in the file”. Manually installing the bases.cav file did work last week but not today.
So what do I do now? I am not eager to go through uninstalling and re-installing again.
Is anyone else experiencing similar problems?
I split and moved your post from the “Comodo AV Database update page” topic and moved it to the AV Help board.
[at]MikeO232: Does my post here solve your problem?
I updated from CIS v5.10 to v7.0…4142 on my Windows 7 PC, and then auto updates stopped working, even though manual updates worked OK. With the helpful clues from Sanya IV Litvyak, I looked for the Comodo task in Task Scheduler (on my admin account). Like clockwork’s PC, Task Scheduler showed in the Last Run Result column “Tried to execute the function, but contradicting triggers avoid it from happening”. Here is how I worked around the Comodo bug.
At first, I tried to modify the “COMODO Signature Update {…}” task. This didn’t work because CIS would revert some of my settings after reboot. Therefore, instead, I unchecked the Advanced Settings > General Settings > Updates > “Check for database updates every” item. This disabled the above task in Task Scheduler.
Next, I exported the above task to “My COMODO Signature Update.xml”, then created a new task by importing the same file. In the General tab, I changed “Configure for” (from Windows Vista) to Windows 7. I changed the triggers to be simply “At startup”. I unchecked all the check boxes under the Conditions and Settings tabs. Simple! I verified by looking at the Last Run Result column under Task Scheduler (run as an admin) that this worked for every reboot! Note that the main CIS GUI shows the time of the last signature update file, not the last signature update check.
Next, I wanted AV signature updates every 6 hours, but only when the CPU is idle. I had previously been frustrated with AV updates causing audio playback problems. However, if I changed Conditions and Settings to achieve this, it would also delay or prevent the AV update at startup. Therefore, I created a new task “My COMODO Signature Refresh” by exporting and importing my above modified task. In this task, I modified the trigger to be “At startup”, but delayed for 6 hours and repeat every 6 hours indefinitely. I changed the Conditions to start the task only if the computer is idle for 5 minutes, and not wait for idle. I changed the Settings to: if the task fails, restart every 30 minutes, and attempt to restart 11 times. This means that it will try until the next 6-hour repeat. Now, AV signature updates occur exactly as I like!
I looked at another PC still running CIS v5.10, and I noticed that it does not use Task Scheduler for updates. CIS v7.0 provides the hooks to fully customize when updates occur. However, I consider it a bug that automatic AV signature updates fail completely unless users use a work-around like mine.
