The title pretty much says it. After BitDefender updates, it suspends services to install them. After installation is complete, the services are resumed. I noticed today, though, that after every scan the Behavioral Scanner remains disabled (as indicated by the view accessed in Advanced View > Antivirus > Shield > Scanner Settings), even if it was enabled previously. Since BitDefender updates often, this is a serious issue; for me and whoever else has this problem.

I have this problem too

Same here, reported as a bug
