A real shame - I like Comodo Antivirus and I’ve tried a few!
Very odd - as mentioned earlier, a different article on the Comodo site by ‘admin’ dated 2020 is giving a link for XP to download Comodo Antivirus too? >
Why you need a Windows XP virus protection program

I’m having the same problem as Eloise and I may have identified the problem.
For me the updates started failing on approximately Nov 2. I got the same errors as shown on her image.
I found that I got a new certificate on Nov 2
C:\Documents and Settings\All Users\Application Data\Comodo\Cis\wpTemp\certupd\authroot.stl
C:\Documents and Settings\All Users\Application Data\Comodo\Cis\wpTemp\certupd\whitelist.json
If I open the certificate, it show the Effective Date as tomorrow (Friday, September 10, 2021 9:09:29 AM).
I hope this means that after the effective date has passed that I will be able to update again. I’ll try to post here tomorrow with my results.
In the meantime, I manually updated by downloading the Base.cav file for ver 5.8 & newer from:
So now I’m much closer to being up to date. The downloadable database is only updated every 2 days. Its ~560 Mb.
FYI, I also run this on WinXP SP3 and my version is: 12.0.0.6818, which I think is the last version supported on Win XP.
Eloise, you can find your version by looking for the ? button (lower right on my version), click it and pick ‘About’. There you will see your version of the software as well as the version of your database. This is also where the link is to import the database I downloaded above.
If any of the forum mods/gurus know anything about the certificate, can you confirm my findings and maybe why a new one came in with a future effective date?
Thank you for the info and help Bawdyn - appreciated.
Found it. I am using:
Product Version 12.0.0.6870
Will await an answer to your question below:
“If any of the forum mods/gurus know anything about the certificate, can you confirm my findings and maybe why a new one came in with a future effective date?”
Must have been some kind of brain fog… That certificate says its effective date was in September, but my brain saw November. So it wasn’t set to be effective in the future.
That said, the modified date of the authroot.stl and whitelist.json files is Nov 2, 2021, which is when I started not getting updates. So something happened then.
In the meantime, I manually updated by downloading the Base.cav file for ver 5.8 & newer from:

Not as convenient as the automatic incremental updates, but better than no updates. As long as you have broadband and a high enough download limit, of course.
