    What is Antivir, and Who are Avira?

    Avira Antivir 2011 Free Reviewed One of the main complaints about premium anti-virus products is that they take up too many resources and demand too much control of your PC. This has led to the mushrooming of free AV software, such as AVG, Comodo and Avira.

    Operating in the industry since 1988, Avira (who were previously known by the unwieldy H+BEDV Datentechnik GmbH) has just released its free 2011 release of its popular Antivir series of anti-virus software, which offers real-time on-access scanning, automatic updates and a quarantine, as well as tools for scheduling scans.

    However as is always the case with free security software, there is a perceived element of risk; if it’s free, why would the software be any good?

    User Interface

    Rating Average

    Avira Antivir 2011 Free Reviewed With a simple user interface, you shouldn’t get lost or confused using Avira Antivir 2011. A useful desktop shortcut provides access to the Avira AntiVir Control Center, which in turn displays a status overview of recent updates and scans, and provides access to the various protection options such as deciding what depth of scan you wish to run or when to schedule a full scan to run.

    All manual scan-related options are accessed via small disc-like buttons; despite the clarity of the Avira AntiVir Control Center user interface, these buttons are not immediately obvious.

    Avira Antivir 2011 Free - test scan results A popular anti-virus choice with an impressive legacy, Avira AntiVir 2011 is worth downloading and installing in any of its guises, free or premium. While the free version focuses on the nitty-gritty of anti-virus tasks, the premium release adds the Webguard to prevent you visiting dangerous websites, active anti-phishing tools and the MailGuard email protection system.

    Ultimately, this is an anti-virus utility. Many similar applications have failed at the basics of running a scan and finding a threat, but in testing on a sandboxed system Avira AntiVir 2011 performed well, detecting threats on an external device with the standard scan as well as finding a threat on the system drive with the active Guard tool (as pictured).

    As such, Avira AntiVir 2011 is recommended!
