However, Kaspersky Anti-Virus, tested by all five of the labs I follow, managed a near-perfect 9.8 points.Looking at other free antivirus products, Avast and AVG both participated with all five labs, including the tough MRG-Effitas, and earned 9.7 and 8.4 points respectively.A similar feature in Avast Free Antivirus 2017 kicks in automatically if it detects you've installed another antivirus product. To start, its score in Virus Bulletin's RAP (Reactive And Protective) test almost precisely matched the average of products I follow. I track four of the many tests performed by researchers at AV-Comparatives.As always, I pay close attention to test results from independent labs around the world. Every product that passes one of these tests receives at least Standard certification.During installation, you see the unusual option to install the product in Compatible mode, which means that all of its on-demand features are available but real-time protection is turned off.You can, of course, turn real-time protection on and off at any time. Well, multiple real-time protection systems working simultaneously could interfere with each other.
However, as far as measurable antivirus protection goes, this version isn't an improvement.
Those that go beyond the basics can earn Advanced certification, or even Advanced .
In those four tests, adaware took two Advanced ratings, one Advanced, and one Standard. My aggregate score calculation puts adaware at 8.4 of 10 possible points, which isn't too bad.
A left-rail menu holds icons for accessing various program functions.
Note, though, that the vast majority of functions are marked as upgrades, meaning that you don't get access to those functions in the free edition.
Antivirus products use different techniques for real-time malware scanning.
