Cannot open CAVS

I tried opening my CAVS 1.1 tonight for the first time in months. I click the Launchpad icon then I click AntiVirus under the “Your Installed Applications” heading then I click the “Show Application Window…” button. A DOS box pops up for about 1 second then closes and nothing further happens. The application window does not open.
The Comodo Firewall is running fine.

Thank you,



You REALLY should upgrade to version 2.0.X of CAVS beta. V1.1 has not seen any development or upgrades for almost a year. I don’t even think that there are AV definition updates available for V1.1. There is no support committment from Comodo for V1.1

You can download the latest version from

Hope this helps,

Will do - I was just leary of the “Beta” designation.

Thank you,


Don’t be - it’s far more stable that v1.1 ever was, IMO. Technically, Comodo’s download page for v1.1 referred to it as a Beta as well…

2.0 is more stable, faster, stronger, installs & uninstalls far more smoothly, requires less system resources when running, and so on. Much better. It does have its issues, but the HAL.dll issue of previous versions has been resolved - that was probably one of the big kickers…
