Since yesterday, Bitdefender seems to make my PC crash/hang at boot
Windows explorer process is frozen. I suspected Bitdefender because the icon in tray was greyed with "service issue" message on mouse hover
Many reboots were no success. I had to Uninstall Bitdefender to make windows boot again
I didn't install windows 10 security updates for Meltdown/Spectre by the way
Any idea if this is caused by some recent update in engine in the last 48h ?
