So just like back in October, tonight I hit the update button on the AV engine and it told me I needed to restart my system. Upon restart the system froze after the Comodo engine loaded. Having been through this before I took the bases.cav file out the repair folder and copied it over to the scanners folder and restarted. I attempted to update again yet had the same error occur. On the 8th at 6:04am the update worked fine yet whatever was put out since then seems to be causing another freeze. The bases.cav file from the repair folder works fine. Anyone else having this problem?
