I've been keeping an eye on BDIS-2106, on a couple of friends' systems for about three months; one a new Windows 10 box and another the free upgrade over 8.1 and each running in full all-default settings. (They pitched in on a 3 PC license.) Their overwhelming no-issues issues is shocking.
I've been running two trials on my 10 test system and my 7 production system (was BD-Free) for a few days. I've got 'em in Paranoid and all-Aggressive, custom on-access and many other settings tweaked to my liking.
Today, ~360 files (!) were downloaded and installed upon reboot which included the Main Interface, Agent and Security Service, the latter going from 20.0.23.1251 to 20.0.24.1276, for example.
Interestingly, in About the build went unchanged - 20.0.24.1290.
I haven't run it long enough for all the problems to show up yet. I hope something shows up soon.
