I wish that there was an option for automatic updates only at boot-up. Now that CIS has AV heuristics, I would use this option to avoid interrupting other running applications. I boot my PC every day, and I use the manual update when not running my normal applications, which just fit within the PC’s RAM. If an update occurs when my normal applications are running, my PC thrashes the disk immensely to run the update from virtual memory. My PC becomes about a 100 times slower for several minutes, making it unusable.
Avira supports this option by supplying an executable for updates that the user can schedule at logon using Windows Task Scheduler (choosing the run as administrator attribute for limited accounts). I already use the Comodo firewall and HIPS. I really need this update option before I can switch from Avira to the Comodo AV.
I understand your point here, but may I ask what will happen once COMODO starts releasing 30 minute database updates? You will be missing those new signatures until the next day, or until your next reboot.
