Lifehacker (New York, March 23) – At age 14, future Illinois alumnus Marcin Kleczynski had a problem: After downloading video games from shady online sources, he accidentally infected his family computer with malware. Kleczynski taught himself to code, and what started out of necessity eventually grew to be its own product and company. Malwarebytes has a team of over 320 employees, and its various products have been downloaded about a half billion times.
