    Started by simple,

    Had this sitting around and thought I'd see what happens w/it here! Goal is to remove the kernel based protection, from inside the kernel (driver must be loaded). Or make any of the functions in the picture work.Any solution w/driver loaded is valid - patching, custom driver to unload protection, etc. X86.sys or X64.sys must be loaded.REQUIREMENTS:- Vista x86/x64 & newer (no xp) - Admin Privs - Test Mode Enabled INSTRUCTIONS: This requires driver test mode enabled. Before running, from an admin cmd prompt type the following, then restart -bcdedit /set TESTSIGNING on bcdedit /set loadoptions INTEGRITY_CHECKS_DISABLEDGood luck! MY_NAME_IS_LOADER.rar
