Ranking of antivirus software that are basically free
Search engines can find you web pages for those antivirus software which include search terms such as "free" but can they verify that its really free? No! And that is where Goonnoo articles come in where we rank only the best, forever free and/or really free services/ stuffs found online. We always try to make our list full of providers that offer the most and/or the best things for free. This article also follows the same philosophy.
Representative Image for Microsoft Defender
There are not much articles on the internet about those antivirus software whose full version is genuinely free forever. So, most of the time, you will be left with those antivirus programs that:-
- ask you to buy a paid plan for even a small feature like displaying the location of the threat in your device
- take too much time to download/ install and makes your system slower
- are only a free trial version
- require an upgrade for even a simple extra feature such as speed optimization, system cleanup etc
- ask for your full name and email to download the software
- are incompatible with other antivirus software
- won`t do what it promises to do
We decided to write this article so that you could avoid these time consuming and frustrating experiences of the internet world. Please not that while all of the listed antivirus programs in this article are for Windows PC, 360 Total Security also works for Mac and iPhone. We will write about free antivirus apps for samsung phone, other android based devices and chromebook in a separate article.
Ranking of absolutely free for lifetime antivirus
Immunet is an antivirus/ antimalware by Cisco which is based on one of the most effective, safest and most trusted antivirus engine called ClamAV and proprietary cloud based detection whose full version is genuinely free for as long as you wish. As it is a community driven antivirus, all the member`s systems get protected if any one of the member`s system is affected by a virus. So, you as well as your family members or friends will be protected if all of them use this software.
There are 3 scan modes namely Flash scan, Custom scan and Full scan. You can also disable any popup notifications or messages about threat detection/ quarantine etc. while playing games or watching movies by first clicking on "Settings" and then on "Game Mode" under "Notification Settings" from the antivirus dashboard. If you have any questions, there is a community forum where you can either search for the answer or ask a new questions for yourself.
One of the factors that differentiate this antivirus software from other popular ones is that since it is cloud based, the download and installation is faster and does not slow down your computer while it sits in your computer. Similarly it is also compatible with other antivirus software such as different variations of Kaspersky, Avira, AVG, Macafee, Norton etc. in Windows XP, Windows Vista and Windows 7. In addition to scanning for viruses, it reports and quarantines other malwares such as Trojan in real time and notifies you through a notification pop up.
This best free antivirus is available for Windows 7, Windows 8/ 8.1, Windows 10, MS Windows Server 2008 R2, MS Windows Server 2012 and MS Windows Server 2016.
2. Microsoft Defender Antivirus
Microsoft Defender Antivirus (formerly known as Windows Defender Antivirus) is the most effective, most reliable and safest built-in antivirus for Windows 10 PC which is totally free. It comes with the Windows Operating System as a full featured antivirus software which is capable of protecting your Windows 10 laptop or desktop from a variety of threats better than any other antivirus software. While this software was not considered effective in Windows 8 and earlier versions, it is considered to be an excellent free antivirus program for Windows 10.
It is capable of protecting your machine in real time by automatically scanning and updating in the background. This stand-alone antivirus software which comes 100% free with the Windows Operating System is also compatible with other antivirus software in which case it will run in passive mode. With this mode on, defender still scans for viruses but does not take any action. This antivirus uses latest technology such as machine learning and big data along with Microsoft`s own cloud infrastructure to detect and block any threat more effectively and faster than other third party antivirus programs.
Defender also protects your computer from Potentially Unwanted Application (PUA) such as ad injection, browser toolbars etc. You can also use this program to scan for emails and archived files such as Zip files. In addition, with Controlled Folder Access, memories, folders and files of your computer are protected against unauthorized access by unwanted applications. Lastly, if you want the Defender to not scan a particular item, you can add an exclusion for it. But note that those items could contain viruses which will compromise the security of your machine.
3. 360 Total Security
360 Total Security is an Antivirus Software with extra features such as speeding up your device`s performance, cleaning up plugins & junk files to save disk space and a desktop organizer for PCs for tidying up your desktop icons (which you can choose to not show in your desktop). You can scan for viruses and optimize your machine`s performance with one click by running "Full Check" from the dashboard of the software. Regarding virus scan, there are three modes - Full scan, Custom scan and Quick scan which will scan for system settings, common apps, running processes, startup items and system critical files. The quick scan is pretty much through although not as time consuming as a full scan.
After the scan is complete, you will be able to see a list of items to be resolved, categorised as risk items and system anomalies. Also, if you want to view the details of an individual item, such as type of threat, description, file path, path in registry, suggestion etc. you can click on the exclamation (!) mark alongside each item.
Although you will see relatively more number of extra notifications for upgrade, third party software installs etc. (which you can safely close) than other antivirus software while using this software, a few of these messages are also related to preventing your system from being affected for example by viruses, trojans etc. and for downloading security updates for your system (although not as effective as virus scans for us).
This antivirus is available for Windows, Mac and iOS (iPhone) and also has an Internet protection plugin for browsers like Microsoft Edge which helps in detection of phising/ Trojan sites and protecting you while you shop online.

The smart scan is faster and gives result within minutes. You will see your safety status after the scan is completed and you can also send an optional feature request right from the software interface.
