There are more reports of x64 bit users having the same issue on system startup after the latest db updates.
Can you please post the DB version you are currently using ?
thx for your help after you watch my video you will know if i turn on the anit virus function after boot will got freeze & can’t click anythings , such as i.e or my files…
Same issues here. Both of my 64-bit Vista machines are having all types of issues running today. I uninstalled Comodo on both systems and everything runs great. I reinstalled Comodo on both systems and the problems came back…but ONLY after updating to the newest virus signatures and then rebooting.
My 32-bit Vista machines are working perfectly…even with newest signatures and reboots.
I would not worry to much, you still have Defense+ to alert you on suspicious things…
Can you work on your system normally if you set AV real-time to disabled ?
I am on the 1776 virus definitions now and everything is working with the scanner Disabled. I just moved it to Stateful and my system is semi-locked up. I get the wonderful spinning blue circle and some hard drive activity, but nothing really happens. It just doesn’t work.
I just rebooted into safe mode, started up Comodo, and was able to set the Virus scanner back to disabled. I then rebooted and everything is working beautifully.
I just set it back to Stateful and everything got messed up again. I guess I’ll leave it Disabled until Comodo figures out a fix.
Same problem here with Vista 64. Just started today. Have to go to safe mode, run, msconfig, disable comodo under services to get computer running. But that disables all comodo including firewall. Must be latest virus definitions.
Comodo - Can you roll back to last definitions until problem solved?
This happened to me as well. The whole computer freezes a few seconds after start up. After uninstalling the antivirus module the computer starts without a problem.
The only new software I installed was the new nvidia video drivers that were released on the 21th of this month. I haven’t had the time to confirm if it is the cause of the conflict because I spent most of yesterday reinstalling windows and all my applications.
EDIT:
Forgot to include my info, running Windows 7 RC x64.
I had the same problem from this morning…took me a while to figure out it was Comodo that was freezing up. I disabled CIS and everything was running fine again.
so i go to safe mode to disable the anti virus function everything will be solve :‘( my another notebook PC also using CIS but X86 version but nothings happen & works normally , so i am sure it’s the latest X64 anti virus definition’s problem , so can anyone solve this problems coz i really support Comodo product , but this times make me lost a lot of time to setup :’(
after you watch my video you will know 
afraid got virus…
