How to Update Antivirus Definitions

I have Firewall version 3.5.54375.427 but can find nowhere to update the antivirus definitions as referred in the Help file. Am I blind? Please help. Thanks (:SAD)

Did you install CIS with AV module? If not, then install the AV module from the Add or Remove Programs.

Many thanks for your quick reply and the screen pictures. Evidently I don’t have the CIS with AV module - but where is the Add or remove Programs page you mention on Comodo Firewall - I cannot find it? Blind!?

Also should I preferably delete the Firewall and then download/install the free CIS version??

But I have AVG AV/A-Spyware which is working well - would this interfere with the Comodo AV? (:LGH)

Add or remove Programs refers to the Windows function, not CIS/CF. There you will be able to change your installation if you wish to add the AV module to your CF, making it a full CIS. In other words, you don’t have to delete the Firewall if you want to add Comodo AV, as far as I know.

You shouldn’t run AVG along with full CIS / Comodo AV, you have to chose one of them. :wink:


If using both with their active protection on, yes. But 1 is enough.
