Avira Free Antivirus 2015 review

Avira’s free antivirus is a bit more conventional in its layout than Avast, its main competitor. It uses a list of menu options down the left-hand side, with context-based settings windows in the main part of the control screen. If you're looking for security suites, see our group test: what's the best security software?

Avira also offers a launcher, which details which modules are installed and which available. We suggest this is of more use as a marketing tool for upgrades than an aid for customers, but it’s a quick way of starting up modules.

Setting up scans is straightforward, though the selection icons are rather small, and there are many common profiles, such as full scan, quick scan and scans of specific drives, set up for you. At first sight, it appears Avira bundles a firewall with its product, but this turns out to be an integrated front-end to the Windows firewall.

File scans can be scheduled and by default there’s a quick scan set to repeat every 168 hours or, as we techies call it, weekly. We reckon a quick scan could benefit for being run more frequently than this.

Avira also provides a trial version of its System Speedup app, which looks at junk files, the registry and privacy issues, but you only get one run, before you have to pay. Free Avira antivirus software is available for Android, iOS and Mac OS as well as Windows.

Avira Free Antivirus 2016 review: Performance

Scanning our 50GB basket of files took one hour and four minutes to examine 398,910 files. This equates to a scan rate of 103 files per second, sitting the program in the middle of the field. A repeat scan completed in 57 minutes, though looking at only five files fewer. This indicates that there isn't any file tagging going on, so the scanner scan ignoe unchanged files.

These results are broadly in line with those from AV-Test, where the same scan engine, taken from Avira’s Antivirus Pro 2015, scored a perfect 18.0/18.0. This is exceptional, though the site’s test results have been getting closer to the perfect score for a while, now.

Breaking down the category scores, Protection, which measures the performance of the software against established and zero-day threats, produced perfect scores against both types. While it’s true to say that the industry average on these tests is a high 98 percent and 99 percent for the two categories, Avira is one of only six products to score a double 100 percent.

Performance measures any speed hit caused by the software during typical daily use. AV-Test measured no delay at all in its tests, which doesn’t tie up with our result, where we saw a noticeable increase in copy time of 41 percent, though that was when scanning.

Finally, the Usability score, which looks at false warnings or detections, showed no errors throughout the tests, including in the one million plus samples used to show up false detections.
