Company History and Business Evolution

Avast UK traces its roots to the original Avast Software, founded in 1988 in Prague, Czech Republic, by Pavel Baudiš and Eduard Kučera. The name 'Avast' derives from the nautical term 'Avast!' meaning 'stop!' or 'hold!'—a fitting moniker for a company focused on stopping cyber threats. The early years were marked by the development of the first antivirus program for Czech hackers, which quickly gained international traction. In 1996, the company officially incorporated and began offering free antivirus software to home users, a disruptive model that fueled rapid user growth. Avast UK was established as a strategic hub to manage operations, partnerships, and talent acquisition in the English-speaking market. Key milestones include the acquisition of AVG Technologies in 2016 for $1.3 billion, which expanded Avast's user base to over 400 million, and the subsequent acquisition of Piriform (CCleaner) in 2017, enhancing system optimization capabilities. In 2018, Avast went public on the London Stock Exchange, raising significant capital for further innovation. The company's evolution continued with the 2021 merger of Avast and NortonLifeLock (now Gen Digital Inc.) in a multi-billion-dollar deal, creating a cybersecurity powerhouse with over 500 million users. Throughout these phases, Avast UK has remained a center of excellence for research, threat analysis, and customer support, driving the company's mission to protect digital freedom. The UK office has also pioneered initiatives in ethical hacking, privacy advocacy, and threat intelligence sharing, cementing its role as a leader within the broader cybersecurity community.
