Baudis’ baby is Avast, the anti-virus software that sits on more than 400 million computers and smartphones around the world. Like the similar products McAfee and Norton also developed in the late 1980s, it’s designed to prevent cybercriminals and spies from installing data-pilfering tools on computers. The main difference is that Avast is free and only available online, not in retail stores. That “freemium” model has lifted Baudis’ company to giddy heights, culminating in its 2018 London Stock Exchange IPO, which set it on a course to become a $4 billion business and has taken Baudis’ net worth to $1.4 billion as of June 2019.
