Avira
Avira antivirus programs, which were first launched in 1988, are based on a scan engine named "Luke Filewalker", referring to Luke Skywalker. On 17 October 2008, a major update to the scan engine was released, which increased scanning speed by 20%. 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 issue, 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.
