Millions of Avast antivirus software users can apply to get a piece – though probably a very small one — of the company's $16.5 million settlement with the Federal Trade Commission over allegations of deceptive marketing practices.

According to the FTC, Avast claimed it used a special algorithm to remove identifying information before transferring the data to its clients.

Avast's alleged privacy violations, uncovered by PCMag and Motherboard, resulted in a $16.5 million fund that will be sent to customers who purchased its software between 2014 and 2020.
