CIS insists on restart for signature updates to take effect, even after restart

Comodo Internet Security 3.14.130099.487 keeps insisting on restart for signature updates to take effect, even after multiple system restarts! “About” screen shows Virus Signature Database Version as 3482. The “Summary” screen shows the virus database has been updated on 2/9/2010 (the last time I successfully updated). Today (2/28/2010) I saw the updates in progress, then got the “You need to restart for signature updates to take effect” message. However, after several system restarts, it still shows the virus database has been updated on 2/9/2010. Clicking on “Update Now” (in the “System Status” pane) immediately displays the “You need to restart for signature updates to take effect” message. How to I get this update to take effect? ???

Looks like you have a corrupted av download.

There are two solutions to solve this:

Both of them will get the latest full AV database. After the reboot you will have to get the latest incremental updates; usually that is only several hundreds of kBytes.
