Today, Avast has over 500 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.

Mobile continues to grow

Going from strength to strength, Avast adds 30 million new users to reach a total of more than 230 million active users worldwide. The company also welcomes a new investor, CVC Capital Partners, which values Avast at 1 billion USD; on the mobile front, Avast buys startup Inmite and adds 40 mobile developers to its mobile business. Meanwhile, Avast Mobile Security reaches 100 million downloads faster than any mobile security app in Google Play history, and AV-Comparatives ranks Avast as the most popular mobile security provider in North America, South America, and Europe, and third in Asia. New product launches: Avast 2015, with four new features (Home Network Security, Secure DNS, HTTPS Scanning, and Smart Scan), Avast SecureLine VPN for Android and iOS, Avast GrimeFighter, and Avast Ransomware Removal. Avast reaches 500 employees and opens new offices in Beijing, Hong Kong, and Seoul.

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 secure.me 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).

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 Download.com. New product launches: Avast Free Mac Security; 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.

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).

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.

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.

International sales & support focus

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

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.

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.

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.

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.

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 Vlček's R&D supervision).

Launch of free Avast

Co-founder Eduard Kučera 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.

McAfee uses Avast engine

ALWIL Software provides the Avast antivirus engine to McAfee, which licenses it for use in its own line of McAfee antivirus products – proving the effectiveness of Avast antivirus technologies with the "Powered by Avast engine" logo on the McAfee VirusScan boxes. Also, ALWIL hires its first tech-support specialist, Pavel Mourek.

Awards in all categories

Avast antivirus is one of the first three antivirus programs globally to win Virus Bulletin's VB100 awards in all testing categories. Virus Bulletin magazine is highly recognized as a leading independent authority on computer security, and even a single VB100 award is difficult to attain.

First antivirus for Windows 95

A young Ondrej Vlček (current Avast CTO) joins ALWIL while completing his university studies. He writes the first antivirus program for Windows 95.

A 'company' is born

Founders Pavel Baudiš and Eduard Kučera, free from the socioeconomic constraints of the former regime, finally transform ALWIL Software from a 'cooperative' into a joint partnership 'company'.

Velvet Revolution

The Velvet Revolution and new Czechoslovak independence from the Soviet Union bring economic freedom to business endeavors. In the preceding years, organizations were not allowed to have 'company' status and had to remain only a 'cooperative'.

First tool against Vienna Virus

Pavel Baudiš, then a researcher at Prague's Mathematical Machines Research Institute, encounters a sample of the Vienna Virus and, intrigued by it, writes a program able to remove it. He then shows it to colleague Eduard Kučera and, together, they start ALWIL Software cooperative, which releases the first Avast antivirus. Due to the oppressive regime, they are unable to form a 'company' at this time.
