IRL Name: 
Marcin Kleczynski

Marcin Kleczynski is the CEO and founder of Malwarebytes. He created Malwarebytes Anti-Malware to address the alarming amounts of malicious threats that were slipping by most major security vendors undetected based on his experience as a technician. The first freeware he created was “About Buster” which cleans a common infection known as About:Blank and that typical anti-viruses at the time could not fix or clean. Then, as he was getting through college, he and his college roommate started writing a utility called RogueRemover. It tackled a specific type of infection known as rogues, which are basically scams to try and steal your credit card information by tricking you into downloading a fake anti-virus software and warning you about a supposed infection that doesn’t really exist. RogueRemover ended up becoming the engine that got Malwarebytes Anti-Malware going.


He launched the first Malwarebytes Anti-Malware version last January 21st, 2008.


He hates IObit so much for stealing Malwarebytes' database.
