I’ve been trying into the query of which free antivirus is the most effective for nearly 10 years now, and the one option to reply is by comparative exams with arduous knowledge, protecting in thoughts that the packages themselves are continually altering and being up to date, and that the image that emerged from final yr’s exams, say, could have modified with the extra up-to-date spherical of exams, and so forth.

We’ll flip to “av-comparatives.org” for our knowledge, since they repeatedly run what are arguably the net’s finest and most complete antivirus exams. As I write this in Jan 2016 I’ll use the newest variations of their exams, carried out inside the final 6 months of this writing.

The contenders: a scan of a number of of the exams they carried out reveals a transparent image of who the ‘real’ gamers are. Free of charge antivirus packages, the highest three are Avira, AVG, and Avast. (Observe: I debated whether or not to incorporate Panda free antivirus, which looks as if it desires to be a contender, however determined to skip it as it’s clearly ‘not there yet’). To be able to present a body of reference, I will even embody the take a look at outcomes of the highest three paid antivirus packages, which will also be recognized with a cursory inspection of the outcomes: Kaspersky, BitDefender, and Eset. I will even copy the apply from av-comparatives, of contemplating Microsoft Safety Necessities as a management, the thought being that since it’s now offered pre-intalled with on many Home windows PC’s, you would wish to put in one other antivirus program in it’s place provided that it’s the case that this new program offers vital further safety.

The query I’m trying reply:  merely, what’s the finest free antivirus program, and how does it fare in comparison with the paid packages.

The analysis standards: typically talking, the three issues I cared about have been (1) The detection price: i.e. how possible it’s to catch viruses, (2) Efficiency: i.e. how a lot of the system assets did it drain; and (3) The speed of false positives: i.e. how possible it’s to ‘catch’ issues that it shouldn’t. All of this data was out there within the av-comparatives knowledge, though the exams didn’t essentially correspond one-to-one with my standards and different variables have been additionally concerned.

The exams that we checked out: we as a rule, and since we have been scripting this in January 2016, we solely wished to have a look at exams carried out inside the final 6 months of 2015 (there have been no exams carried out in 2106).

Additionally, as a result of that is an investigation into the most effective free antivirus, we excluded any take a look at that didn’t embody all three free antivirus packages (Avira, AVG, and Avast).

Subsequently, we regarded on the following exams. Solely those under match our standards

  1. Actual-World Safety Take a look at August – November 2015
  2. Efficiency – Take a look at October 2015
  3. File Detection and False Positives Take a look at – September 2015
