How To Geek: We warned you at the beginning of the year that many of your browser extensions are spying on you, tracking what you are visiting, and even inserting ads into pages. These aren’t just no-name developers either: even Avast, one of the most trusted antivirus vendors was in on the game.
Before we go even one step further, it’s important to note that they recently disabled the spying “shopping” feature in their browser extension. So if you are running the latest Chrome with extensions updated, you are fine. For now.
