I've not heard of "SecurityHealthHost.exe" before. I've heard of "SecurityHealthService.exe" but not this... and none of my other computers have that file on it... just this one.
However, Kaspersky Total Security, Malwarebytes, and TDSSKilller are coming up blank. I'm in Safe Mode and about to run RogueKiller, but if anyone has any ideas... I'd appreciate it. If this isn't a virus/malware and I'm just spinning my wheels, I'd like to know.

As well as the advice from Richbuff, a little more info: https://www.file.net/process/securityhealthservice.exe.html .
C:\Windows\System32 is the only place SecurityHealthHost.exe should be.
