Avira AntiVir

Avira AntiVir Personal is for personal use only and free of charge. Like most antivirus software, it scans disks for malware and also runs as a background process, checking each opened and closed file. It can detect and possibly remove rootkits.[2] It also performs Internet updates (daily by default) in which it opens a window, with an advertisement suggesting that the user purchase Avira AntiVir Premium or Avira Premium Security Suite. Avira updated all its products to version 10.0 in March 2010.

As a free service, Avira offers a bootable rescue CD to all users, regardless of whether they have any installed Avira products (free or non-free), and irrespective of the machine’s operating system. This CD contains its own bootable Linux-based operating system and the AntiVir program with its latest virus database. If a computer cannot be booted, the CD may be used to boot the machine into the AntiVir program, then to scan for and remove detectable viruses and other malware, thereby possibly restoring normal boot and operation.[3]
