Although both Windows 10 and Windows 11 ship with a built-in security tool called Windows Security, it’s still best to use third-party security suites. Third-party security programs like Avast, Avira, Kaspersky, etc., offer better protection against various security threats.

The good thing is that most leading security companies have their free security products. These free security products were more capable than Windows security when it came to defending against viruses, malware, PUP, adware, and more.

So, if you are looking for ways to improve the security of your device, you have landed on the right page. This article will list some of the best free antivirus software for Windows 10 and 11. So, let’s check out.

10 Best Free Antivirus Software For Windows

Important: Don’t use multiple security programs on your PC; using only one security product at a time is recommended.

1. Avira Free Antivirus

Avira Free Antivirus

Well, Avira Free Antivirus analyzes the entire system with a single click of a button. This program has an easy-to-use interface that allows even less technical users to configure and use it easily.

This program is based on a cloud scanning system, which means that any suspicious detections will be directly sent to an online server and checked in real-time, and then the response is sent to the program on the user’s computer.

On the downside, Avira’s free antivirus slows down the device. However, considering that it is a free tool and that its malware detection rate is high, the slowdowns are not a high price to pay.

2. Avast Free Antivirus

Avast Free Antivirus

The free version of Avast Antivirus is an award-winning product that provides real-time protection for the devices on which it is installed. This antivirus works by checking the programs’ codes and detecting the dangerous ones.

The program can block phishing websites, malware, ransomware, viruses, and adware and detect unwanted, outdated programs. In addition, Avast Free checks to see if other devices connected to the user’s network were safe or not, like printers, telephones, TVs, tablets, and so on.

Kaspersky Security Cloud

Kaspersky Security Cloud is a free antivirus program that defends your PC against viruses, infected files, malicious applications, and suspicious sites. The free version of Kaspersky works fine as it guards your PC against various security threats.
