Hi,
I have just installed Bitdefender Internet Security 2012 and I can't change the Antivirus options.
(Sorry if I not naming the UI items correctly, but I'm using it with a Portugese-BR translation)
On home screen, i click on Settings, then I choose the antivirus tab on the left and then the shield tab on top.
The customize checkbox is checked, and I can't unckeck it. Also, if I click on "Change" button (the second one), a dialog pops up, but it won't save any of the changes I make. I click OK on the dialog, it closes, I click again on Change button and the settings are back to how they were before.
One more thing on the same tab: on the lower section, "Active Virus Control", the slider is set to off and I can't turn it on.
It's running on Windows 7 64 bits and all other options seem to work correctly.
Best regards,
