ar.voicefive popup won't go away

Hello,

A few days ago, I had a pop-up from ar.voicefive. I googled it and it turned out to be a browser hijacker. I don't know where it could've came from because my laptop is only used for school purposes as well as watching Netflix. I don't download things unless they are school related from my school website. I've followed the steps in this forum:

but it hasn't seemed to stop. The popups actually increased. Please help! I want to stop this before it gets worst.
