Thank you Draclvr. That definitely answered my question about the malwarebytes. The ad attacks have stopped, although I'm not sure what I did to stop them. I ran Spybot, Adaware, CCleaner, and Malwarebytes. I'm still getting a few messages from Malwarebytes about stopping malicious sites but not as many. I think I'm out of the woods. I'll definitely be more careful about downloads in the future but I thought what I was downloading was safe but obviously not.
Anyway, fingers crossed, maybe the worst is over.
You laugh because I'm different
I laugh because you're all the same
Of all the things I've lost, I miss my mind the most.
