I'm having trouble with the firewall of bitdefender because it blocks some windows updates such as "Update for Windows 7 for x64-based Systems (KB2488113)". The Windows Help and Support offered help and said:
If you use a different firewall, check the information that came with the software to see how to add these websites to your firewall exceptions list:
http://*.update.microsoft.com
https://*.update.microsoft.com
http://download.windowsupdate.com
But I don't know how to add websites to bitdefender firewall exception list. Though I have solved the problem by temporarily disabling bitdefender's firewall to install the update, I'd still like to know how to add websites to bitdefender's firewall exception list so that I don't have to disable the firewall whenever these kinds of windows updates are installing in my computer. Waiting for any reply. Thanks.
