A member of the Clearwater tech hub, Malwarebytes offers a host of cybersecurity solutions for a variety of platforms.

Clearwater is home to Malwarebytes, the formidable tech company whose products protect businesses and individuals worldwide. Although the company was formally established in 2008, it began earlier as the brainchild of wunderkind Marcin Kleczynski, the company’s CEO and founder. As a teenager in 2004, Kleczynski informally started the company after an antivirus solution failed to protect his parents’ computer from a virus. Kleczynski then solicited and received the free advice of techies and cybersecurity experts online, an act for which he was so grateful that he decided to return the favor a million-fold by inventing a free anti-malware solution. Thus Malwarebytes was born, and millions of businesses and individuals are forever indebted to Kleczynski for his act of kindness.
