I got this yesterday also. Took all day & night to fix. Malwarebytes will get it, but you have to do it a couples of times and other things as well.
Reboot your computer and click on malwarebytes shortcut icon to start the program BEFORE your computer completely reboots--ie;, before the Antivirus Pro takes over. Run the scan, delete what results are there--BUT DO NOT REBOOT computer as malwarebytes says to! Then do EVERYTHING this page link tells you to do.

Step 6 is VERY important!! It caught one of the last traces of it (where you run a harddrive search for sysguard)
THEN!! Run spybot search and destroy and it gets the last registry key remaining. Then it should kill it.
Yes, extremely tough to kill and doesn't allow you to do ANYTHING.
