Computer keeps getting adware/malware?

I was dumb and attempted to download a minecraft texture pack or something a few months ago and ended up with adware. I downloaded superantispyware and it detects "adware tracking cookies" all the time. I can have it delete them and scan and have more five minutes later. I have all cookies receiving turned off now. I downloaded malwarebytes today and it deleted alot of "PUPs" and I thought that fixed it but it didn't. The adware shows up as "ads by quickshop" and is saying "dnsunlocker" by the ads now. I've deleted everything in my documents, downloads, even recycle bin that could be the problem. Anyone have a solution?
