How can i get rid Personal Guard 2009 anti-virus?

i dont know how it got there, i turned on my computer this morning and then it poped up saying i got 12 infections (which i know are fake) along with windows security center saying i have no virus protection. i use AVG and it says nothing is wrong with my computer. its really annoying because every 15 minutes Personal Guard keeps popping up. i’ve tried doing a system restore but it keeps on failing.
i wanna know how i can get rid of this without downloading some spyware removing because i know they wont work unless you pay, trust me i’ve tried that today. so please dont tell me to go download

or some BS like that.

Malwarebytes.org IS FREE. they have a pro version but you do not have to pay for the free version and they both do the same thing except
the pro version has a IP blocker
Superantispyware.com FREE same thing as above free works as good as the paid only not real time protection.
See below for Microsoft solutions and you will see they tell the same thing-
