Comodo antivirus reports it is out of date in Windows XP

what’s the AV database version you have in About box?

It is version 28711

Tested same v6526 on XP SP3, don’t see any problem in general.
So looks like system specific issue.

May you please share snapshot of following folder?
c:\Documents and Settings\All Users\Application Data\Comodo\Cis\wpTemp\cavsedb\

folder attached as requested

Can you please try to delete these and run update again?

still get signature updates error. Should I now copy them back to folder ?

We will have to investigate.
Please upload following files on some shared online space like google drive for us to investigate:
You will find a .cav file under following:
c:\Documents and Settings\All Users\Application Data\Comodo\Cis\

Also, copy all files under
c:\Documents and Settings\All Users\Application Data\Comodo\Cis\wpTemp\cavsedb\


I couldn’t find a cav file under option 1 but have copied all the cav file in wpTemp to

Sorry, my mistake:
You should find under following folder:
c:\Documents and Settings\All Users\Application Data\Comodo\Cis\signatures


I have just added it now. It might take a few minutes to appear due to file size

It should be there now

Yes, it’s there.
Thank you. Please allow us to investigate and get back to you by early next week.

I am not sure what has happened, but my Comodo has just updated for the first time in about 3 weeks and Windows is no longer showing error. Is it due to something that Comodo has done ? I would like to know in case the problem reoccurs
