Avira Antivirus Is the Lightest Antivirus Software
By on December 24th, 2009

Will it slow down my system?, is a question antivirus vendors are often asked by worried customers. Indeed, antivirus utilities are infamous for having an adverse impact on system performance. A new report released by Av-comparatives a leading antivirus software testing firm, provides us the answer to this oft-asked question.

Av-comparatives-Antivirus-Performance-Test

Av-comparatives used 16 popular antivirus utilities and measured the impact they had on various activities like file copying and downloading. Fully defragmented hard disks were utilized on each occasion and external factors like network and temperature were neutralized as far as possible.

None of the antivirus utilities had a significant impact on encoding/transcoding and archiving/unarchiving speeds. However, eScan, FSecure, G DATA, Microsoft and Trustport slowed down file copying significantly (more than doubled the time required to copy a file). Thankfully, due to fingerprinting technologies, all of them but eScan performed impressively on subsequent runs.

When it came to slowing down application installations/uninstallations Bitdefender, G DATA and Trustport were the biggest culprits. Trustport also increased application launch times by more than 100%. These three were joined by AVG in the file downloading hall of shame. AVG, Bitdefender, G DATA and Trustport more than doubled file download durations.

Throughout the tests Avira performed admirably and this was reflected even in the WorldBench scores. eScan, Trustport, Bitdefender and G DATA once again found themselves at bottom of the pile.

Thanks to an outstanding all round performance Avira was the overall winner. Kingsoft, F-Secure, Sophos and Kaspersky were the other products which made it to the top five.

    AntiVir Premium is one heck of a security tool, but those nag screens in the free version are really annoying. In any case, it's definitely the lightest of all free antiviruses that I've tried. :]

    I have used Avira for a ling time. It is the best antivirus I came across.

    The only problem I have using Avira, is that the option to include a file in exception when the guard detects a suspicious file does not work. I had to manually add files to exception.

    I would have guessed that microsoft security essentials was lighter but my old favourite pips it again….

    It's quite funny that Norton which is supposed to be super light ….. isn't.

    It probably only feels light because it used to be so big and slow. A bit like Win 7 now feeling light only because we had Vista I suppose.

    The good: Norton AntiVirus 2010 steps lightly on the CPU, while at the same time increasing in recent years, a detection system based on the reputation of a new behavioral detection
