Ads, Ads everywhere!?

[bob bobson]

Recently, out of nowhere, i've been getting tons of ads popping up. I use Google Chrome as a browser. Ads open in new-tabs and normally appear whenever I click links of any sort, Once clicking a link they either take over that tab as an ad or pop up a new tab for the ad. What is causing this and how should I go about getting rid of it?
I've tried it on sites where it has never happened before, it's happening on every website I use. I've ran Malwarebytes-Anti Malware and CCleaner Pro scans multiple times in hope they'll fix anything. Nothing so far :/
