US Senator Faults FTC for Dropping Ball on Antivirus Data Harvesting

'No consumer would realistically have an inkling that their antivirus software could be selling their browsing data,' US Senator Mark Warner said after a joint investigation from PCMag and Motherboard examined the data practices of Avast's free antivirus software.

US Senator Mark Warner (D-Virginia) is questioning why the FTC hasn't investigated the data collection practices of antivirus companies following a PCMag-Motherboard investigation into the privacy risks of Avast selling the customer browser histories to third-party companies.

"It's increasingly clear that the FTC hasn't kept up with how these markets for data operate, and appears to be unwilling to use its authorities to do so," Warner said in a statement.

On Monday, PCMag and Motherboard published a joint investigation examining Avast's free antivirus products and how they can expose your website clicks to corporations and market research companies. Although the antivirus company claims it "de-identifies" the collected browser histories before selling the information off, the same data can still be analyzed to link a person's web activities to their real identity.

In response to the investigation, Warner said: "Time and again we've seen that consumers are totally unwitting to the ways their data is being collected, commercialized and sold." He not only pointed to antivirus companies, but also web browsers and VPN services, which have attracted scrutiny as well over potential spying risks.

Avast Mind Sharing Some Data

"Yet in each of these cases we've repeatedly seen trusted intermediaries undermine the privacy and security of consumers," he added. "No consumer would realistically have an inkling that their antivirus software could be selling their browsing data and—even more sensitive information such as mouse movement— to an array of third parties."

In the case of Avast, the free antivirus software is capable of scanning every site your browser is visiting as a way to warn you of any malicious or fraudulent activity. However, the same feature can also harvest your browser history, along with any sensitive search terms you've made through Google or Bing, according to PCMag's investigation.

The good news is that users can easily opt out of the data collection by going into the antivirus software's privacy settings or turning it off on install. However, Avast's marketing and privacy promises around the data harvesting may convince people otherwise; the company has been recently asking all users to opt into the data-sharing when the Avast subsidiary in charge of monetizing the browser histories, Jumpshot, has been selling access to the data for million of dollars.

In his statement, Warner said: "Congress can't afford to ignore these issues any longer." The senator previously introduced other legislation to crack down on deceptive website practices that can fool you into handing over your information. But the US still has no federal digital privacy law in place.

The FTC declined to comment, saying "investigations are nonpublic." But the regulator told Motherboard: "However, we are very familiar with how these markets for data operate, and will not hesitate to take appropriate action as necessary where we find conduct that violates the laws we enforce."

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
