Congratulations - I just spend two days rescuing my PC after an AVaste PRO upgrade last week (approx. 20-21/4 2016) - the disk became unbootable and loop crashed BSOD - error 0xc0000225 "The boot selection failed because a required device is inaccessible" - it took me two working days to figure out that your AV fucked up my drive. No repair, system restore or anything helped - except the uninstall of AVaste.
Anyways - just a warning to other AVaste PRO users, if you get this sort of problems, you may not have noticed the automatic update so just uninstall and you'll probably be fine.
Needless to tell that I'm upset
