OK, after disabling MB from starting with windows, reboot, same number of thread with FF and Chrome BUT NOW, KAS take nearly all the CPU with no disk activity, even after 5 minutes... It return to normal after loading the MB console to reactivate it at next reboot.... After a reboot, all back to normal PS: yesterday after posting, I had to add VLC.EXE to the MB trusted list. Same issue I had with FF and Chrome before. Pretty sure I will have to add other applications to the trusted list in the coming days... Lots of fun ahead it seem

Ok, this problem is relate to the Kaspersky Removal tool that remove the "volsnap" string require by VSS in the following UpperFilters key [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{71a27cdd-812a-11d0-bec7-08002be2092f}] "UpperFilters"=hex(7):76,00,6f,00,6c,00,73,00,6e,00,61,00,70,00,00,00,00,00 Since I still have Kaspersky, the key now contain: klbackupdisk volsnap "UpperFilters"=hex(7):6b,00,6c,00,62,00,61,00,63,00,6b,00,75,00,70,00,64,00,69,\ 00,73,00,6b,00,00,00,76,00,6f,00,6c,00,73,00,6e,00,61,00,70,00,00,00,00,00

OK, Kaspersky Total Security 20.0.14.1085(g) and MB Premium 4.0.4 with all options actives for both products, under Win 10x64 build 1909 I have added the exclusion listed here for KAS in MB and for MB in KAS by Maurice Naggar, including CHROME.EXE and FIREFOX.EXE in MB. I finally had to add Mozilla Firefox\UPDATE.EXE in MB since it also froze while trying to start firefox. It really look like KAS and MB are fighting... At this point, both Chrome and Firefox seem to work but Firefox show 7 threads in Task Manager with one open tab and Chrome show 21 for 2 open Tabs. No idea if it was like that before upgrading to KAS 20 or not. Also, just discovered I now have an Error 0x81000203 while trying to access System Protection tab in the System Property dialog box. At this point, I am not sure if I have a stable system or not. This system would stay up for weeks without problem before. We'll see
