Avast Software s.r.o. is a Czech multinational cybersecurity software company headquartered in Prague, Czech Republic. Avast has more than 435 million users[3] and the largest market share among anti-malware application vendors worldwide as of January 2018.[4] The company has approximately 1,700 employees across its 25 offices worldwide.[3] Avast was founded by Pavel Baudiš and Eduard Kučera in 1988 as a cooperative. It had been a private company since 2010 and had its IPO in May 2018.

In July 2016, Avast acquired competitor AVG Technologies for $1.3 billion. At the time, AVG was the third-ranked antivirus product.[5]

It is listed on the London Stock Exchange and is a constituent of the FTSE 250 Index.


Avast was founded by Eduard Kučera and Pavel Baudiš in 1988.[6] The founders met each other at the Research Institute for Mathematical Machines in Czechoslovakia.[6] They studied math and computer science, because the Czech Republic would require them to join the communist party to study physics.[6] At the Institute, Pavel Baudiš discovered the Vienna virus on a floppy disk and developed the first program to remove it.[6][7][8] Afterwards, he asked Eduard Kucera to join him in cofounding Avast as a cooperative.[7] The cooperative was originally called Alwil and only the software was named Avast.[9]

The cooperative was changed to a joint partnership in 1991, two years after the velvet revolution[10] caused a regime change in Czechoslovakia. The new regime severed ties with the Soviet Union and reverted the countries economic system to a market economy.[7][9] In 1995, Avast employee Ondřej Vlček wrote the first antivirus program for the Windows 95 operating system.[7] In the 1990s security researchers at the Virus Bulletin, an IT security testing organization, gave the Avast an award in every category tested, increasing the popularity of the software.[7] However, by the late 1990s, the company was struggling financially.[6] Alwil rebuffed acquisition offers by McAfee, who was licensing the Avast antivirus engine.[6]

By 2001, Alwil was experiencing financial difficulties, when it converted to a freemium model, offering a base Avast software product at no cost.[7] As a result of the freemium model, the number of users of the software grew to one million by 2004[7] and 20 million by 2006.[9] Former Symantec executive Vince Steckler was appointed CEO of Avast in 2009.[11] In 2010, Alwil changed its name to Avast, adopting the name of the software,[9] and raised $100 million in venture capital investments.[12] The following December, Avast filed for an initial public offering, but withdrew its application the following July, citing changes in market conditions.[13] In 2012, Avast fired its outsourced tech support service iYogi, after it was discovered that iYogi was using misleading sales tactics to persuade customers to buy unnecessary services.[14] By 2013, Avast had 200 million users in 38 countries and had been translated into 43 languages.[6] At the time, the company had 350 employees.[15]

In 2014, CVC Capital bought an interest in Avast for an undisclosed sum. The purchase valued Avast at $1 billion.[16][17] Later that year, Avast acquired mobile app developer Inmite in order to build Avast's mobile apps.[18] Additionally, in 2014 Avast's online support forum was compromised, exposing 400,000 names, passwords, and email addresses.[19][20] By 2015, Avast had the largest share of the market for antivirus software.[13] In July 2016, Avast reached an agreement to buy AVG for $1.3 billion.[21] AVG was a large IT security company that sold software for desktops and mobile devices.[22] In July 2017, Avast acquired UK-based Piriform for an undisclosed sum. Piriform was the developer of CCleaner.[23] Shortly afterwards it was disclosed that someone may have created a malicious version of CCleaner with a backdoor for hackers.[24] Avast had its IPO on the London Stock Exchange in May 2018, which valued it at £2.4bn and was one of the UK’s biggest technology listings.[25]


Avast develops and markets business and consumer IT security products for servers, desktops, and mobile devices.[26] The company sells both the Avast product line and the acquired AVG-branded products.[27] As of late 2017, the company had merged the AVG and Avast business product lines and were working to integrate the corporate departments from both companies.[28] Additionally, Avast has developed utility software products to improve battery life on mobile devices, cleanup unnecessary files on a hard drive, find secure wireless networks[29] or create a VPN connection to the internet.[30]

Avast and AVG consumer security software are sold on a freemium model, where basic security features are free, but more advanced features require purchasing a premium version.[27] The free version is also supported by ads.[31] Additionally, all Avast users provide data about their PC or mobile device to Avast, which is used to identify new security threats.[6] Antivirus scanning, browser cleanup, a secure browser, password management, and network security features are provided for free, while firewall, anti-spam, and online banking features have to be purchased.[32][33] According to PC Pro, the software does not "nag" users about upgrading.[32][30] About 3% of Avast's users pay for a premium version (10% in the US).[6]

The Avast business product family includes features for endpoint protection, Wi-Fi security, antivirus, identity protection, password management, and data protection.[28] For example, the desktop product will look for vulnerabilities in the wi-fi network and run applications suspect of having malicious hardware in an isolated sandbox.[34] The Avast Business Managed Workplace monitors and manages desktops, and assesses on-site security protocols.[28] The company also sells management software for IT administrators to deploy and manage Avast installations.[28]


PC Magazine gave the Avast free antivirus software an overall score of 8.8 out of 10 and gave AVG a score of 8.4.[27] The review said Avast gets good lab test results overall and has many features, but its password manager is a bit limited.[27] In tests by the AV-TEST Institute, Avast 2017 received six out of six points for protection and usability, and 3.5 points for performance.[27] A review in Tom's Guide said the free Avast antivirus product has "good malware protection" and has a small footprint on the system.[33] The review said Avast has a competitive set of features for a free antivirus product, but the scans are slow and it pushes users to install the Google Chrome browser.[33]

The Avast antivirus product for business users received 4 out of 5 by TechRadar.[34] The review said the software had good features, protection, configuration, and an "excellent interface," but took up too much hard drive space and didn't cover mobile devices.[34] According to Tom's Guide, the mobile version is inexpensive and feature-laden, but some features are unreliable or do not work as expected.[35] PC Magazine said the mobile version "has just about every security feature you could want" but was difficult to use.[36]

AVG, which was purchased by Avast in 2016, has also generally performed well in lab tests.[37] AV-Test Institute gave AVG six out of six points for usability, 5.5 points for protection and 5.5 points for performance.[37] However, AVG scored 81.05 in Virus Bulletin's lab tests, which is slightly below average.[37] The software is "very good" at detecting malware, but "disappointing" in antiphishing screening.[37] A review in Tom's Hardware gave the AVG software seven out of ten stars.[33] The review highlighted that the software has a small system footprint and has good malware protection, but does not have a quick scan option and lacks many additional features.[33]
