Support for the kernel stopped at 3.11 I believe. There is a way to get it running, I have tested it on a vb. You can try the following:
Download from here -
Comodo AVDouble click on the deb file and install it.
Then open a terminal and do:
sudo /opt/COMODO/post_setup.sh
Start Comodo from the desktop.
Ignore any errors, click on the Antivirus tab, and do Update Virus Database.
When that is complete, exit Comodo from the tray area.
Download -
http://www.bondoffamily-net.com/~kinta-chan/techknow/DownLoad/src/beta/driver.tar?date=20140325 and copy it to /opt/COMODO/driver.tar replacing the other driver.tar file.
Open a terminal in the folder where
driver.tar is and do:
sudo cp driver.tar /opt/COMODO/
Then open a terminal and do:
sudo /opt/COMODO/post_setup.sh
again.
Start Comodo from the Desktop. All should be well now.
