A while ago, I started having a problem with the AV part of CIS premium: scanning files was taking a very long time, even hours for tiny files.
And every time I tried to scan a file, the program would try to update the virus definition, even if it had just finished updating.
Worst of all is that lately the virus database updates have been taking forever, or just fail and never update.
The last update shown for me is 22 hours ago, and for whatever reason, manual updates are erroring out.
I am currently using v12.0.0.6882, which I read is the most stable.
Outside of virus updates, I don’t think I have any issue with this version.
Is the issue that older versions are not updating properly anymore? Or is it perhaps some Comodo CDN issue?
Will upgrading fix the issue?
Lastly, why does AV need to update definitions before every scan?
We have tested in our environment with multiple platforms and there is no such delays.This might be due to network issue.So if you still had this issue in the sense Please don’t hesitate to ping me.
Have a nice day!
Check C:\ProgramData\Comodo\Cis\signatures for the presence of .cav files there should only be one.

By default the [url=https://help.comodo.com/topic-72-1-766-9161-Scan-Profiles.html#settings_cust_scan_options]scan options[/url] for each scan profile to check for av database updates before running is enabled.
