Even though I have automatic updating enabled I occasionally check for security updates for my system (win 7x64). This AM I noticed that an important security update was available so I allowed it to do so. However during the process I received a notification that my virus and firewall were turned off and then a screen popped-up giving me the option to enable both which I did. Never experienced this in the past with updates and this caused me concern. Ran MBAM as a result but it found nothing as well as SAS.
Here is the update

I don't know if I am over-reacting but nowadays "better safe than sorry". Would appreciate any input from BC.
