Avast, an antivirus program with more than 435 million users worldwide, said it will stop collecting and selling the private web browsing histories of its users following a joint investigation by Motherboard and PCMag into the sale of that data. In addition, Avast said it will completely shut down Jumpshot, the subsidiary company it used to sell this data.

Our investigation found that Avast, through a subsidiary called Jumpshot, made millions of dollars following its users around the internet. Jumpshot told its clients, which include Microsoft, Google, McKinsey, Pepsi, Home Depot, Yelp, and many others that it could track “every search. Every click. Every buy. On every site.”
