Hi,
there seems to be an issue with CIS Antivirus component after installing Microsoft’s latest update for Windows 7 (two updates plus the release of SP 1 as of 22 Feb 2011).
My system, a DELL XPS 1340 laptop, with Windows 7 Pro 64bit came almost to a halt after installing the above mentioned updates. In detail, those updates are:
KB2484033 (update) - installed correctly
KB2488113 (update) - installed correctly
KB976932 (Windows 7 Service Pack 1 for 64bit systems) - installed correctly
KB2387530 (update) - caused error during installation
After installing the Windows updates as listed above and after restarting the laptop, the system was rendered almost unusable, responding extremly slowly, almost coming to a halt. Unable to execute applications or only with very much delay after which they would not respond any more. The task manager did not start up after choosing the corresponding option from the task bar (right click on task bar, then selecting from the menu). It was not possible to shut down the system either through the different options available in Windows (Start menu, F4 on desktop, etc.). In short, the system was basically not responding.
Only when I disabled the Antivirus component of CIS Premium, all of the sudden all programs started working correctly, although I received an avalanche of security request from CIS (strangely, because only the Antivirus was set to disabled, not so the firewall or defense functions). I did not understand why it would ask e.g. if Firefox and many other common applications should connect to the network when those applications had been run under CIS before, having been already confirmed to CIS as OK (“remember answer” was always checked.
This is just to let others know that there’s an issue in case they run into the same trouble. From here on I do not currently know what the next step will be, but I suggest COMODO looks into this and provides an update for CIS ASAP, as I’m sure there will be many others with this issue.
BTW, CIS never popped up a message asking to allow the newly installed applications to be executed or access the network. I was completely silent until I disabled the Antivirus component! I had restarted the laptop about 5 times, so there was enough opportunity for CIS to react to the updates. It didn’t and the system slowed down almost immediately after reboot.
Cheers,
