AVG Technologies B.V. [ 1 ] is a brand of cybersecurity , privacy, performance and utility software applications for desktop computers and mobile devices developed by Avast , a part of Gen Digital . As of 2026, AVG offers anti-virus, a secure browser, firewall, anti-tracking, VPN, and device performance software for Windows, MacOS, Android, and iOS. [ 2 ] Many are offered as freeware , earning revenues from advertisers and from users that upgrade to paid versions to access more features. AVG was founded in 1991 in Czechoslovakia . [ 3 ] In the early 2000s, AVG expanded internationally and used money from venture capital investments to fund a series of acquisitions. AVG went public on the New York Stock Exchange in February 2012. Avast acquired AVG for $1.3 billion in July 2016. In 2022, Avast and Norton became Gen Digital . AVG Technologies was founded by Tomáš Hofer and Jan Gritzbach in 1991 under the name Grisoft in Brno , Czechoslovakia. [ 3 ] Initially, Grisoft sold IT equipment and third-party software, in addition to its own antivirus product. [ 4 ] Grisoft grew as the country loosened its international trade policies, so it could exchange technology with companies in Europe. [ 3 ] By 1998, Grisoft had 13 employees. [ 5 ] Grisoft later expanded to the US market, creating an American company called AVG. [ 5 ] Grisoft also expanded to the United Kingdom , the Netherlands , Germany , and other countries. [ 6 ] For a time, the company was focused on bulk sales of antivirus software to computer manufacturers that sold PCs with Grisoft's software pre-installed. [ 5 ] It started marketing software directly to consumers in 2006. [ 7 ] In 2008, Grisoft changed the name of its parent company to AVG, the name already used for its software and for its American subsidiary. [ 8 ] TA Associates invested an additional $200 million into the company that year for a minority stake in the business. [ 9 ] In 2001, Grisoft was sold to a venture capital firm Benson Oak Capital. [ 3 ] The firm then sold a 65 percent interest in Grisoft to Intel Capital and Enterprise Investors for $52 million in 2005. [ 3 ] [ 10 ] [ 11 ] The investments were used to fund a series of acquisitions. [ 3 ] Grisoft bought spyware company Ewido Networks in 2006 [ 12 ] and browser security company Exploit Prevention Labs in 2007. [ 13 ] In 2009, AVG announced the acquisition of Sana Security, which analyzes software behavior. [ 14 ] This was followed by the acquisition of mobile security startup DroidSecurity and iMedix Web Technologies in 2011, [ 15 ] [ 16 ] parental control software company Bsecure in 2012, [ 17 ] and remote monitoring company Level Platforms in 2013. [ 18 ] AVG Technologies filed an initial public offering in February 2012. [ 19 ] Additionally, former Mozilla CEO Gary Kovacs was appointed CEO of AVG. [ 20 ] He led the effort to create a simple one-page privacy policy that discloses what data the company collects from users and what information about free users it sells to advertisers. [ 21 ] In 2014, AVG announced the acquisition of Location Labs, a cybersecurity company focused on mobile devices, for an estimated $220 million. [ 19 ] AVG was acquired by Avast for $1.3 billion in July 2016. [ 22 ] [ 23 ] By this time, AVG had 600 employees, $155 million in annual revenue, and 95 million users. [ 3 ] The combined entity became the world's largest antivirus company, with an estimated 20% of the market. [ 24 ] There were Avast or AVG installations on 160 million mobile devices and 240 million desktop computers. [ 25 ] The new combined entity incorporate their technology into combined software products and developed a new channel program to market them to small business owners. [ 26 ] [ 27 ] A few months later, an American private equity firm, TA Associates , bought a 25 percent interest in AVG for $200 million. [ 3 ] In 2015, AVG acquired the VPN company Privax [ 28 ] and an Israeli-based gallery app company called MyRoll. [ 29 ] It also released new software products for businesses that incorporate the technology of both companies. [ 27 ] In July 2017 AVG acquired Piriform Software , a UK-based company that developed CCleaner , a cleanup utility with 130 million installations. [ 30 ] AVG develops and markets software for IT security, privacy, performance optimization, and other utility services on desktop computers and mobile devices. [ 31 ] It is one of the largest brands of cybersecurity software. [ 32 ] AVG also develops software for data backup , parental controls , and other services. [ 33 ] [ 34 ] AVG produces a variety of other computer optimization and utility software products. [ 32 ] [ 19 ] For example, a browser extension called AVG SafePrice looks for better deals online when the user is on a shopping site. [ 35 ] A majority of AVG's revenues come from free users upgrading to paid versions. [ 33 ] AVG is best-known for its antivirus product. [ 34 ] AVG AntiVirus is a freeware program [ 34 ] that relies heavily on heuristic analysis to determine if a program's code is behaving like malicious software. [ 5 ] [ 36 ] It scans a computer's documents, programs, and emails for suspicious behavior, [ 37 ] then rates each file's risk based on its behavior and alerts the user of files with a high rating. [ 36 ] AVG Antivirus has features intended to protect the user's PC from malware , phishing , and viruses . [ 35 ] It also has firewall, identity protection, anti- ransomware , anti-spam, and webcam control features for paid users. [ 35 ] [ 38 ] [ 39 ] AVG Secure Browser AVG Secure Browser is a web browser that has built-in ad blocker. The browser works on Windows, macOS and Android. [ 40 ] As of 2024 it had approximately 0.02% market share. [ 41 ] AVG PC TuneUp is a software suite for Microsoft Windows computers that allows users to "manage, maintain, optimize, configure, and troubleshoot a computer system." [ 42 ] In May 2012, AVG Technologies issued a copyright claim, referred to as a ' takedown request ,' for a YouTube video of 1987 pop song " Never Gonna Give You Up ", performed by British singer Rick Astley . [ 43 ] [ 44 ] The video was restored within 24 hours by YouTube. [ 43 ] [ 44 ] The video's name refers to the internet meme commonly referred to as ' Rickrolling ,' where someone pranks others by tricking them into going to the video. In 2016, AVG's browser add-on, AVG Secure Search, was criticized as being adware , [ 45 ] for being bundled with other software and mistakenly installed. AVG Secure Search was also advertised to users of the free versions of AVG products. [ 46 ] Some reviews at the time noted that, although the add-on offers legitimate malware-blocking capabilities, the default behavior of changing the web browser's default search engine, homepage, and new tab page to AVG Secure Search was reminiscent of a potentially unwanted program (PUP), problems uninstalling the add-on were reported, [ 45 ] and the add-on could potentially make a web browser more vulnerable to attacks. [ 47 ] Later, AVG fixed these problems in its browser extension. [ 2 ] ↑ "15-12B" . www.sec.gov .
