comodo anti virus

As i write this I just downloaded the program. I am trying to do a scan with no success. An error message “ANTIVIRUS ENGINE NOT INITILIZED” despite the fact that I ran an update. I cannot do anything else. How do I make this program work? I have never ran into this issue. I need help immeadiately!

rtrg, I can only suggest that you uninstall and re-install CIS. You may want to consider downloading the latest AV update directly rather than using CIS itself for the initial update.

Rename the file to bases.cav and copy it in C:\program files\COMODO\COMODO Internet Security\scanners\

Hope this helps
