After doing some research on this forum I noticed that CIS 3.5 had problems updating last year. I checked to see what version we have and we have 3.8. I still get the “Failed to update the virus signature database. Check your internet connection”. We have Microsoft Windows XP 2002 and use NetZero dial up.
Did you import your old 3.5 configuration in 3.8? That may be the cause of the problem.
Can you look what is at shown for the following registry keys for Updatepath and UpdateURl:
HKEY_LOCAL_MACHINE\SYSTEM\Software\Comodo\Firewall Pro\Configurations\0\AV\Settings
HKEY_LOCAL_MACHINE\SYSTEM\Software\Comodo\Firewall Pro\Configurations\1\AV\Settings
HKEY_LOCAL_MACHINE\SYSTEM\Software\Comodo\Firewall Pro\Configurations\2\AV\Settings
HKEY_LOCAL_MACHINE\SYSTEM\Software\Comodo\Firewall Pro\Configurations\3\AV\Settings
HKEY_LOCAL_MACHINE\SYSTEM\Software\Comodo\Firewall Pro\Configurations\x\AV\Settings?
They may be still with the 3.5 paths. The UpdateUrl should be http://download.comodo.com/. The UpdatePath I can’t check as I am 3.9 RC2. Anybody who want to look it up?
