“I was born in Poland but grew up in Chicago. I started the company at the age of 14 after I had accidentally gotten a computer virus on the family computer. It took me three days – with the help from computer forums to clean it up, and that birthed the idea for a faster, better way to protect from malware. I developed the core technology for Malwarebytes and ran it from my dorm room while I got my bachelor’s degree in Computer Science from the University of Illinois.”
