Hello Everyone,
We investigated the problem and here is explanation as what happened. For few hrs on Wednesday, cloud started returning Absent for all vendor look up and as CIS does scheduled cloud lookup for existing vendors to ensure if any is removed from cloud it is removed from local list; it ended up removing vendors from local list.
So in case any existing user who had been affected due to this bug, sees a new signed application, which is not safe by signature but only through trusted vendor lookup and if live cloud lookup fails, he may see alert.
While we are contemplating in providing update to local vendor list via program updates, any one willing to have list updated, can download master list via following URLs:
Steps for replacing:
-
Go to CIS installation folder
%PROGRAMFILES%/COMODO\COMODO Internet Security\database\
-
Rename ‘vednor.n’ and ‘vendor.sha’ and replace with following respectively:
http://download.comodo.com/av/tvl/vendor.sha
http://download.comodo.com/av/tvl/vendor.n
-
Re-start system and you should see complete list in Defense±->Computer Security Policy–>Trusted Software Vendors
Sorry for inconvenience caused.
Thanks
