Messes with your Google Search results--I think they're trying to direct users to certain websites for phishing attempts. Extension will simulate Google Search results by creating two sets of results. I only noticed the issue as the first results were in white, different than my black colored browser/taskbar theme. The first set of results would sometimes duplicate links from the second set. Sometimes I'd have two links to the same YouTube page and or Wikipedia page.

Clicking on some of the links yielded in warnings, and security notices.

Maybe author's just trying to redirect users for a few extra bucks in ad revenue. Or maybe he's out there trying to actually ruin your life.

Shame, was working great. Removing said extension fixed my Google Search results.
