Windows Action Center Malware Keeps Coming Back?

while ago, I got a virus that tried to mimic windows activity center. Since then, I have use malwarebytes anti malware, ccleaner and microsoft security essentials to scan and remove the virus.Usually what happens is that I will be using firefox, and all of a sudden most of my programs would exit, and one of those fake virus scanners come up (Microsoft security essentials also turns off if that is important). I open the task manager, and identify the program. I open explorer (as i can't open mbam, or mse) and delete the file. While it is in the recycle bin, I can open mbam (for some reason, it asks what program to open mbam with, I just pick mbam from the list) and I scan, and remove the threats. Then I empty the recycle bin, and use ccleaner to fix the registries. Lastly, I use mse to scan the computer.Everything works for a while until it comes back again....and again....and again. I've tried the same steps in safe mode and again in regular mode. It's still happening.
