I can tell you as an IT professional in a mom and pop shop who has sold upwards of 1,200 MBAM licenses we're barely able to tread water this morning. This is going to take us days to straighten out and is costing us a *fortune* in unbillable time and resources to rectify.
We're sticking with MBAM - great product and they truly took ownership of their mistake, but it's going to take quite a while for us to recover from their mistake.
A big concern is those residential users who got spooked and are dumping MBAM en masse and going to Norton or McAfee - they are the real ones who will pay in the long run with substandard AV protection.
