AntiVirus Software Virus Is Back!! Help Please.

It was fixed for a whole 24 hours with no more popping up and than it suddenly started up again!!
I still have Malwarebytes on my computer but it won't update. I remember reading something on here that said how to fix that and it worked. Going to Internet Options than LAN settings to change something. and it worked.
than Malwarebytes found the problem and I deleted it and wola! it worked.

but now its back. and i didnt delete Malwarebytes at all. Does anyone know what I should do? My friend suggested Cleaning up my Whole computer so that its like brand new. Would that work?

Please and thank you
