Avira Operations GmbH & Co. KG is a German multinational and family-owned antivirus software company. With an estimated 9.6% of market share according to OPSWAT, and over 100 million customers, Avira was considered the sixth largest antivirus vendor in 2012.[1][2]

The company supports the Auerbach Stiftung, a foundation created by the company's founder Tjark Auerbach. It promotes charitable and social projects as well as the arts, culture and science.[1]


Tjark Auerbach and a colleague set up his first information technology business in Tettnang: H+BEDV, in 1986. The letters H and B stand for Hannelore Auerbach and Betty, the wives of the two founders.[3]

In 1988 H+BEDV Datentechnik released its first antivirus scan engine named AntiVir (formally named "Luke Filewalker" referring to Luke Skywalker).[3]

In 1990 Auerbach, along with Martin Ritter and Norbert Huth, converted the company into a GmbH with six employees.[3]

In 2006 H+BEDV Datentechnik GmbH and its sister company AntiVir PersonalProducts GmbH and Avira GmbH merged into the company named Avira GmbH. The product kept the name AntiVir.[4]

On 17 October 2008, a major update to the scan engine was released, which increased scanning speed by 20%.[5]

On 12 June 2013, Avira announced that Travis Witteveen replaced Auerbach as CEO effective July. Auerbach remained as the majority shareholder.[6]

Avira competes in the antivirus industry against BullGuard, F-Secure, Frisk, Kaspersky, McAfee, Sophos, Symantec, Trend Micro among others.


Virus definition cleanup[edit]

Avira periodically "cleans out" the virus definition files, by replacing specific signatures with generic ones, resulting in a general increase in performance and scanning speed. A database clean-out with the size of 15 MB was made on 27 October 2008, causing problems to the users of the Free edition because of its large size and slow servers of the Free edition. To solve the problem, Avira improved the updating process by reducing the size of the individual updatable files, resulting in the delivery of less data in each update. Nowadays there are 32 smaller definition files that are updated regularly in order to avoid peaks in the download of the updates.[7]


Avira has removed their own FireWall Technology in Version 2014,replace it with the management of Windows FireWall(started with Windows 7/8/8.1),because in Windows 8, the Microsoft Certification Program forces the developer to use interfaces introduced in Windows Vista.

Protection Cloud[edit]

Avira Protection Cloud (APC) was first introduced in version 2013. The aim of APC is improving detection with less impact on system performance due to the use of cloud computing. APC was initially released as a sneak technical preview to selected testers.

After the initial preview, Avira implemented this technology in all paid 2013 products. When APC was first implement in Version 2013, its only used when the users perform a manual quick system scans. Lately,this technology has been extended to the real-time protection, which subsequently improve the Avira's score in the AV-Comparatives September and later Report. [8]


Avira offers its antivirus engine in the form of a software development kit to implement in complementary products. Strategic and technology partners of Avira are Canonical, CYAN Networks, IBM, itelligence AG, Microsoft, novell, opswat, Synergy Systems and others.

Avira offers three security products for Microsoft Windows:

  1. Avira Free Antivirus: This edition is free of charge. It runs as a background process which checks every file opened or downloaded. Like many antivirus programs, it can run a full or custom scan to check the computer for malware in order to remove them. It updates its virus definitions automatically every day by default using the Internet. Contains popups-ads.
  2. Avira Antivirus Premium: The Premium edition includes all features of the Free edition plus:[10]
  3. Avira Internet Security: The Internet Security edition includes all features of the Premium edition plus:[10]

Avira offers a set of free tools including a "Rescue System" utility used to write a bootable CD which can be downloaded as an EXE or ISO file. It has its own Linux-based operating system so it does not depend on the one on the host PC. It can be used to clean an unbootable PC, and is able to find malware which uses the host's operating system to hide (e.g., some rootkits). The tool contains the antivirus program and the virus database current as of the time of download. It boots the machine into the antivirus program, then scans for and removes malware, also restoring normal boot and operation. It is updated frequently so that the most recent security updates are always available.[11]

Consumers products for other platforms[edit]

Avira offers Avira Free Android Security for Android v2.2 and later, as well as Avira Free Mac Security for Mac OS X.

Avira used to offer "Avira Free Unix/Linux" for Unix or Linux Platform, but has discontinued the product as of 30 June 2013. New licenses are no longer available, but existing customers will receive updates until 30 June 2016.[12]


AV-Comparatives awarded Avira AntiVir Premium with the highest score, the "Advanced+" distinction, in February, May, and August 2008, earning it the 2008 "AV Product of the Year" award. This large-scale comparative test saw Avira achieve an "excellent" score for its proactive detection performance. In the "Speed" category, Avira made it to the winner’s podium. In the "Summary Report 2010" it received the Silver award for 99.5% detection rate.[13]

In January 2008, Avira AntiVir was given a rating of 6.5 out of 8 in tests for detection and removal of rootkits and 71% for proactive virus detection by Anti-Malware Test Lab; both scores qualified for "gold" status, the highest award.[14] Avira achieved the highest Malware Detection rate, along with G-DATA Antivirus, 98%, and was one of five products that achieved a 90% or higher spyware detection rate in the latest AV-Test performed in February 2010.[15] AV-Comparatives also awarded Avira with an Advanced+ rating (the highest) in their latest test.[16] Avira had the highest signature and proactive detection rates in all major independent antivirus tests.[when?] In April 2009, PC Pro awarded Avira Premium Security Suite 9 six out of six stars and a place on its A-list for Internet security software.[17] In August 2009, Avira AntiVir Personal Antivirus achieved a 98.9% percent overall malware detection rate, and was the fastest for both on-demand scans and on-access scans conducted by PC World, who ranked it first on its website.[18] Neil J. Rubenking from PC Magazine gave version 10 3.5 out of 5 stars.[19]

Avira was among the first companies to receive OESIS OK Gold Certification.[20] This shows that both the antispyware and antivirus components of several of their products have achieved the maximum compatibility score with widespread network technologies (like SSL/TLS VPN and Network Access Control) from Juniper Networks, Cisco Systems, SonicWALL and others.

Avira has also received VB100 awards.[21]
