Botnet:blacklist

Hello,

I keep receiving pop-up windows every few minutes, with two different warnings.  I have tried resetting my Firefox browser, running Rkill, Malwarebytes, HitMan pro and other potential solutions.  How do I fix this?  I am using a paid subscription to AVG anti-virus.  Note that I added Malwarebytes after this problem started.
