Marcin Kleczynski is a Polish-born immigrant who moved to the US at age of 3 and grew up in the Chicago suburbs. As a kid, he spent much of his time on forums and in chat rooms during the early days of the world wide web. Due to his families financial situation, he couldn't afford to buy computer games, so he downloaded them from the internet and one fateful time his family's computer became infected with Malware. Frustrated that his computer's anti-malware didn't prevent the infection, he took to seeking help from security message boards to troubleshoot and remove the malware by hand. While developing his own tiny solution to his problem, he realized other people could use it too, and so he founded Malwarebytes. In early 2008, his company's first product was released. What began in his suburban home is now an international company with a 750 employees, is used by more than 60,000 businesses and millions of people worldwide. Now, let's hack... Marcin Kleczynski.
