How do I get rid of blue PlaySushi links?

Hi, I was doing some Nexon surveys and I came across this PlaySushi thing, so I stupidly downloaded it and my computer was filled with all these blue links. I would see a world like "Login" and it would be blue and have 2 blue lines under it. I then went into my program files and deleted every PlaySushi thing I could find. I went back on to chrome and I still saw those blue links. I know they were from PlaySushi because when I would put my mouse over them, they would be advertising something and it would say "PLAYSUSHI" at the top. I then scanned my computer with Norton and it said there was nothing there. The next day I was really getting annoyed by the links and ads so I googled: "How do I get rid of PlaySushi links" and I came across this one link where some guy has the same problem. It was a forum and people were telling him to change browsers and scan his computer withe everything he has. Well I tried that, and still I have those blue links. But then I saw people talking about "Malwarebytes" so I downloaded that and I did a full scan on my system and it found tons of adware, so I deleted all of it. But then it said that some files couldn't be deleted and you would have to reboot your computer, so I hit "Yes". So then it rebooted my computer and malwarebytes didn't open up again, so I clicked on it and did a Quick Scan. It found 85 more adware things and I deleted them, but the same thing happened, it said it couldn't delete some files and it would have to be rebooted. I said "no" because I thought the same thing would happen again where malwarebytes wouldn't pop up again. By the way, in my full scan, I ended the scan since it was taking so long, I ended it when it found 145 problems. Should I do the enitre scan next time? Help!
