Problems with removing antivirus pro

T.T I am having great difficulty with removing antivirus system pro. This is the third time it's attacked my computer. The previous two times I was able to remove it by just starting my computer up from a previous memory, but now that I have some important things on here, I don't want to go that rout if I don't have to.

I've downloaded the Malwarebytes' Anti-malware program and I've run it several times. But pop ups keep coming, and porn sights, and ed problem sights, and the program isn't working for me.

Any suggestions?
