There’s security in numbers

More people around the world trust Avast for their security than any other company. That means better security for all of us. The reason is simple: We see and react to more data from more users, so we can make your protection better.










AVAST’s roots go back to 1988, when Czech researchers Eduard Kucera and Pavel Baudiš encountered the Vienna Virus and began their quest to save the world’s computers from it and others like it.
Today, AVAST has over 380 professionals headquartered in Prague, Czech Republic, with additional offices in Germany, the USA, and China, distribution partners in all markets, and a global community of avast! enthusiasts.


Launch of free avast!

Co-founder Eduard Kucera implements an innovative user-community growth strategy based on the principle that all computer users deserve protection from harmful threats, and that computer safety should not be a luxury some cannot afford. Thus, on June 1, ALWIL Software launches a free antivirus solution for home (non-commercial) use. Six months later (January, 2002), a new registration system sees the very first user registration of free avast! antivirus Home Edition.


Opening an online store

The growing free avast! user base generates a need to offer other paid-for solutions effectively online. Thus, ALWIL turns to Digital River’s online sales distribution share-it! New product launches: avast! Bootable Antivirus & Recovery Tool (BART) CD and the (free) avast! 4 Home Edition (under Ondrej Vlcek’s R&D supervision).


One million users

Only 30 months after its first user registration, the free version of avast! reaches one million users. Until this time, it remains uncertain as to whether giving for free what others sell will work, but reaching one million users confirms a successful increase in visibility for the company. ALWIL implements an international reseller channel for its paid-for security solutions. New product launches: avast! Linux version, avast! 4.5 Home/Professional edition, avast! Distributed Network Manager (ADNM), and avast! BART CD 2.0.


SanDisk alliance

As a great way for avast! to reach new users at a time when the internet does not have such high penetration, ALWIL begins cooperation with SanDisk. Thanks to this partnership, avast! needs language localization for all SanDisk markets. Thus, ALWIL hires the first people for in-house localization and support – this is the first step toward avast! becoming an international success in terms of supported languages. New product launches: avast! U3 Edition (for SanDisk) and avast! 4.6.


User base doubles – twice

The avast! user base doubles twice, first to 10 million and then to 20 million by year’s end, in large part due to the availability of more language versions and a number of industry awards for quality. avast! sweeps the SC Awards categories with Best Antivirus, as well as Anti-Malware (European) and Readers’ Choice (USA). New product launch: avast! Linux Home Edition.


One million users per employee

The company reaches 40 million registered avast! users with only 38 employees, for a ratio of one million users per employee, which the company will maintain over the coming years. ALWIL Software transforms into a joint stock company. New product launches: avast! Mac Edition and avast! Windows Home Server Edition.


International sales & support focus

ALWIL puts major focus on acquiring a multinational sales and support team and localizing avast! antivirus and into more languages. The company reaches 50 million registered users and 60 employees. New product launch: avast! 4.8.


Expanding HQ

To strengthen the team, ALWIL hires Vincent Steckler (formerly of Symantec) as CEO. The avast! registered-user base jumps from 68 million to over 100 million, and the company reaches 100 employees. New product launch: the 5.0 series of avast! Free Antivirus, avast! Pro Antivirus, and avast! Internet Security.


Entry of Summit Partners

Summit Partners invests $100 million for a minority share of the company, confirming the unique position of avast! in the global marketplace. Says Han Sikkens, a Principal in Summit Partners, “it is rare to find a company such as AVAST that redefines how an industry does business. We are very excited about the growth prospects of this exceptional company.” ALWIL Software changes its name to AVAST Software, to more closely align the company with the brand, and avast! reaches 130 million registered users. New product launches: avast! 5.0 series, with a new antivirus engine and an optional Silent Firewall and virtualization Sandbox.


Over 165 million registrations

By midyear, avast! has more than 135 million active users and over 165 million user registrations – all with just over 150 employees. New product launches: avast! Business Protection line (with a simplified central administration console); avast! 6.0 series, with new innovations that include: WebRep™ (a website reputation tool), SafeZone (a clean-desktop option for added safety with sensitive online transactions), and AutoSandbox™ (the first automatic virtualization feature offered within a free antivirus).


Great new milestones

avast! finishes the year actively protecting over 170 million PCs, Macs, and Android devices, with just over 200 employees. avast! Free Mobile Security reaches best-rated security app in Google Play, and avast! Free Antivirus achieves the top-downloaded software spot on New product launches: avast! Free Antivirus for Mac; avast! 7.0 series, with new innovations that include Remote Assistance (for giving/getting help to/from a friend with avast!), the avast! Account portal (for overseeing all avast! protected devices), and cloud-based FileRep (a file reputation detection) and streaming, real-time virus database updates.


25 years of making things better

On its 25th anniversary, avast! antivirus claims an industry record by protecting over 200 million PCs, Macs, and Android devices worldwide – and is ranked the most-downloaded product on several major global software portals. As well, AVAST Software (the company) acquires the German company and USA-based startup Jumpshot, gets awarded the Czech Republic’s “Best Employer 2013” in the category of large companies, and finishes the year as the most-profitable IT company in its home country, with just over 350 employees. New product launches: avast! 2014 series, with our new Artificial-Intelligence-driven DynaGen technology; avast! SecureLine VPN (a virtual private network for encrypting and anonymizing web activity); and avast! GrimeFighter (for optimizing/speeding up PC functionality).
