I'm refuring to how they want the only security to work with it is inbuilt microsoft security software
That's bullcrap. MS have simply forced the way security programs should work - by not patching/bypassing the kernel and other core system files. Symantec et al are only having a spew because THEY don't have ultimate control over your system anymore and are forced to rewrite most of their routines to suit a different (more reliable) integration method.
