Avira Operations GmbH & Co. KG is a German multinational and family-owned antivirus software company that provides IT-security for computers, smartphones, servers and networks – delivered as both software and cloud-based services.

Avira’s headquarters are located near Lake Constance, in Tettnang, Germany, and the company has additional European offices in Munich, Bucharest, and the Netherlands. Avira also has offices in Japan and China, as well as an R&D facility in the USA’s Silicon Valley.[2]

With an estimated 9.6% of global market share according to OPSWAT, and over 100 million customers, Avira was considered the sixth largest antivirus vendor in 2012.[1][3]

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]


Virus Definition[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 up-datable 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.[4]

xVDF release[edit]

In March 2014 Avira intend to release a new VDF format xVDF (e(x)tended Virus Definition File),the successor of the nVDF.It force on the loading time and size of VDF The xVDF mechanism the update volume of VDF files to a minimum affect. This allows the VDF files keep as small as possible.it also improve the VDF loading time which minimize the CPU resource consumption when loading the smaller VDF files. xVDF also extended the files to more large numbers (256 for Windows;32 for Android),However the xVDF update mechanism will create an optimize single cache VDF files(local*.vdf) automatically on each update.The scanner engine will only load this single cache files instead of loading and merging all the downloaded VDF files on scan startup. [5]

Advance Heuristic (AHeAD)[edit]


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. [6]


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

On 4 September 2014, Avira announced a partnership with Dropbox, to combine Avira's security with Dropbox's "sync and share" capabilities.[7]
