Popup issue

So for like the past week or so I’ve been getting ads that pop up on my Chrome and when I downloaded a so-called free application JumboDeals. I did comodo search and found out a related tutorial saying that popups would be removed as long as I reset the browser settings and remove some registry files. Should I follow this guide and can you help me check it? I just want to protect my PC from more danger. Or you can show me another way to permanently clean off these popups?
