How often does the A/V update on CIS. Mine seems to connect 2 or 3 times an hour and takes 10 minutes or so to download the updates. According to COMODO website the updates are small and fast!
I do believe it’s every 30 minutes;
How are you connecting to the internet?
Hope this helps

Thanks Jake for your quick reply…I connect using a broadband LAN connection. About 30 mins seems ok for updates but it seems to take a long time to download the update.
Also on the summary screen…being updated right now…seems to be stuck, and yet there is no activity!
Your welcome;
Does this happen daily or once in a while? because it seems to me that it’s just a temp lag…
No just now and then, not every time.
Seems to have come right now! Hey I am in Christchurch NZ, couldnt send you an earthquake or two could I, we have plenty to spare, 4500 odd since Sept 4! LOL!!
LOL 
I’m on the San Andreas Fault Line 
(Southern Riverside, California (USA))
I wouldn’t worry to much about the slow updates; unless it continues to persists continuely, also if it takes more then 30 minutes
Then I would start complaining and putting on the sad face
Hope this helps

On checking updates again, every auto update downloads the same file. BASE-END-USER-v7488.cav. And at 83.2mb is seriously eating my bandwidth up!
I would recommend uninstall and run the clean up utility found here and install again;
If Problem Persists After Re-Install;
start > Programs > acc > cmd (Right click run as admin) > ‘cd %systemroot%’ Without the ‘’ > ‘rd /s temp’ > ‘md temp’ > cd %userprofile% > ‘del /f /s /q %temp%’ > exit
This should fix the issue;
If still persists,
Please Create a Bug Report
Hope this helps!
