Using Hitman to Remove Mandiant Ransomware -- Sloooooooowww, Then Nothin'

I've followed the directions from elsewhere on this site, attempting to remove Mandiant ransomware using Hitman. Everything seemed to be going smoothly, but then Hitman seemed to have stalled while scanning for fragments. I let that process run for over 24 hours, during which no change appeared on the screen. It had found several pieces of malware of assorted types, including Mandiant, but the "Next" button was grayed out.

I've tried twice. The third time, despite telling it to boot from the flash drive, it booted normally.

Not sure what to do next...
