Best Free Antivirus Products for Windows PC in 2019 – NANO Antivirus Free.

Overview

NANO Antivirus protects the user computer in real-time from all types of malware using their Signatures, Heuristics Analysis, Web Protection, and Cloud technologies.

Most of the Free Antivirus products are the lighter or the stripped down version of the main paid product. Some of them are more like a promotion rather than a free version. However, that’s not the case with NANO Antivirus, which is a full-featured Antivirus program.

NANO is what most of the famous Antivirus products of today looked like way back when they were getting famous. When they had few or no paid products to offer. And, their free versions had none to minimal advertisements and promotions.

  1. Forticlient is a solid AV. I have used it off/on for about 4 years now. It has been greatly improved since the first version. In addition to standard AV signatures, it now seems to offer a bit of behavorial detection, and the web filter is excellent. It seems that it has to be connected to a Fortinet appliance before you can submit a file to them, but you can probably submit a file at their website. I agree that it is underrated, and I give it a solid 4/4.5 rating.

    I am an independent malware analyst, and I am not connected with Fortinet/Forticlient.

    Regards,

    • FortiClient has gained some attraction due to the YouTube video reviews in recent years. I remember using it briefly around 2009. It has become a much better and a complete antivirus product now.
      I’m yet to use and review the newly released version 6.0.
