how to remove warning dangerous spyware background?

i do not want to download any other programs. when i downloaded other programs it just messed up my computer more. i could do it manually. i just need the instructions and what to delete. thanx.

in safe mode F8 run malwarebytes anti-malware and SUPERAntispyware,and what they find you
delete it manually. then run ccleaner to clean your pc, and mvregclean, to clean registry.
what mvregclean find you remove because the key is there but not the file ,folder or program.
even you reformat and it finds anything remove dont be afraid.
dont forget when you install this software to update them, and do an update every day
then restore until before you get infected.
