Download Malwarebytes, update it, reboot into Safe Mode, scan. Kills it dead. I deal with that once every other week or so at my job. It's done by cagey motherfuckers; we have an alphanumeric-wildcarded guard against it (it spawns xxxxsysguard.exe where X is a random letter A-Z) and as soon as that gets implemented, it changes to xxxxguardsys.exe.
Also CHRIST MODE, you are damn good. One art please.
