Avira Antivir has received an increasing amount of attention since garnering the highest score of any free security program on AV-Comparatives independent testing service for on-demand testing.
It fares a bit worse on the "Retrospective/ProActive" test, although still better than any of the other applications tested. However, it's hard to find anybody who finds the
virus definition file update speed to be fast: it's notoriously slow. We put
Antivir through the CNET Reviews Labs benchmarking process and came up with some unsurp
rising results.
When running alongside other high-drain processes, such as iTunes file conversion and while running MS Office,
Antivir scored high. CA
Antivirus and Panda 2008 were the top two products, followed by the premium version of
Antivir and then the standard version, but all others tested including AVG
Anti-
Virus, Kaspersky, and Avast fell in behind them.
The MS Office test produced far less staggering results. With
Antivir Personal completing the test in 271 seconds and
Antivir Premium finishing in 270. The fastest of the 12 products, Panda 2008, scored 269.67 seconds, while the slowest, F-Sure, hit 273.33, so Avira was more toward the average here than in the other tests.
Overall, Avira slowed down the test machines somewhat, but it caused less drag on system resources than most--but not all--of its competitors. Boot time tests placed it at an average of 30.85 seconds, one second slower than Kaspersky, two seconds slower than BitDefender, and nearly two and a half seconds slower than the premium edition of
Antivir. In scan testing,
Antivir scored second-fastest after Panda 2008, and nearly three times faster than AVG
Anti-
Virus 8.0.
Combined with its high marks for removing and preventing infections, I remain convinced that
Antivir is the best free
antivirus on the market right now.
