Senator Ron Wyden is investigating why cybersecurity company Avast collects and then sells its customers' browsing data. Avast's free browser plugin is not only designed to protect users, but also takes anonymized browsing history which Avast then uses to provide insights on what groups of users are doing online. The company has 400 million users, according to Avast's website.

"Sen. Wyden's office has reached out to Avast to express concerns about this practice and to learn more about how it operates," a spokesperson for Wyden told Motherboard. "He's considering next steps now."
