“Avira security software” refers to a range of antivirus and Internet security software for the Windows, Linux, FreeBSD, OpenBSD, and Solaris computing platforms by Avira. These applications are based on the AntiVir antivirus engine also known as “Luke Filewalker”, first launched in 1988.

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

Avira GmbH periodically “cleans out” the virus definition files, by replacing specific signatures with generic ones, which results in a general increase in performance and scanning speed. The last database clean-out was made on October 27, 2008, which caused problems to AntiVir Personal users when updating because of its large size (15 MB) and because of AntiVir Personal’s slow servers. For that reason Avira GmbH added an additional 6 GB of bandwidth to the AntiVir Personal Servers and changed the updating process: Nowadays there are 32 smaller definition files which are updated regularly to avoid peaks in the download of updates.
