I'm running BD Internet Security 2015 build 18.15.0.1127 on Win 7/64, 12GB memory and no other AV products. This is also a re-installation of Windows 7 (in place).
About a day after the re-installation, I noticed that Active Virus Control is unchecked (unticked) and when trying to check it, the check mark instantly disappears. Yesterday, I believe there was a Windows notification that security coverage might not be working properly. I checked this morning and the Windows settings are as to be expected (Windows Firewall OFF, etc.)
The same exact behavior also for Intrusion Detection System, but not any other features.
I ran the BD Repair process twice and updated the program version to the latest build, but it made no difference.
Also, I thought the program version gets updated automatically during update... This morning, it was build 18.12... meaning, there were several builds that didn't get updated automatically (my Updates are set to run automatically). Might this be related to a general problem?
Thank you,
JF
