Many thanks, V1. I did learn a bunch (even if it hurt). Your comments about MalwareBytes indeed gave me pause. I wonder if they have cleaned up their act. That they could push out updates without so much as a Beta has me at a loss for words.
Just curious, do you know if the "incident" spread its filth to connected, but partitioned volumes, external drives, etc.? I ask because having an infection is bad, not having a recovery partition or backup volume is catistrophic.
