Best Free Antivirus Programs in 2026
To find out which are the best security programs of 2026, you can read the detailed reviews below. Each review not only gives you an idea of the level of security of the product but also the main security features and how user-friendly the software is, which should help you pick the right security that meets your requirements.
Norton 360 Antivirus
Norton is the perfect solution for people who want to surf the web securely and be totally comfortable with that, but at the same time, they don’t want to get into the technical details of ransomware or phishing. You are able to surf the web, stream media, and buy without experiencing the nagging dread of “should I click this?” because to its robust core security and handy features, such as a password manager and a smart firewall.
Talking about the features, Norton 360 offers quite a few products for a user to utilize. Some of the things you get are a Smart Firewall, cloud backup for your PC, and handy optimization tools.
VPN security is ensured through AES-256 encryption, WireGuard, OpenVPN, and Mimic protocols. The WireGuard protocol also improves VPN connection speeds. Besides this, there is a password manager, dark web surveillance, SafeCam, Safe Web browser protection, and parental control.
Bitdefender Antivirus
Bitdefender Antivirus Plus, the product of choice, not only excels in core protection, but also Bitdefender Antivirus Free for Windows provides essentially the same level of protection for a much lower price. It mostly resembles Bitdefender’s security suite, but you can disable many of its features. Compared to other security suites, commercial antivirus programs offer a plethora of additional capabilities.
Among them, you may find a Wi-Fi security analyzer, a Rescue Environment for recovering from malware that disables the operating system, and a fortified desktop for safe surfing. Although you won’t get any of these functions for free, some people find that the antivirus fundamentals are all they need.
AVG Antivirus Free
AVG Antivirus free edition offers solid protection in a simple-to-use package, particularly suitable for novice users. While it is true that AVG and Avast share the same core security engine, what distinguishes AVG from competitors is its simpler, lighter interface, making it easier for daily users. This software primarily focuses on real-time protection and detection of serious malware, accomplishing this by eliminating unnecessary complexity.
Just like Avast, AVG protects your files against ransomware by blocking any changes to the encrypted files without authorization.
Microsoft Defender
Without Microsoft Defender Antivirus, formerly known as Windows Defender, a conversation on free antivirus software would be incomplete. In the event that your antivirus subscription expires or you don’t have a third-party antivirus program, Defender assumes responsibility for your security. Defender discreetly withdraws to the background if you add or activate another antivirus program.
We’re not really excited about employing Defender to defend you, though. It only obtains a passing score on certain lab tests, while it performs well on others.
Avira
Avira Free Security, similar to Avast, is a complete security suite that can be used for free. While some features remain hidden, you can still view them all. While it performed middling in the most recent set of laboratory tests, it performed well during our hands-on testing of fake and dangerous websites.
While Avira scans for applications that may be at risk due to outdated or missing security updates, the responsibility for fixing these issues ultimately falls on you. A basic password manager, a shopping bargain finder, a VPN with restricted bandwidth, and a thorough privacy settings checker are among the other features. Active protection of ad trackers is also available.
TotalAV
When looking for a free antivirus, TotalAV is a solid choice. That’s because its security applications are a breeze to set up and operate. The antivirus’s settings and capabilities are all well labelled, so using it won’t be a chore.
TotalAV is a very good option for device security as it works with Windows, macOS, Android, and iOS. Its very easy-to-use interface is the main reason why we strongly recommend its apps to beginners. In particular, we like the concise descriptions of each feature and configuration. By doing so, you will never have confusion or overload while using the antivirus.
Final Thoughts
It is difficult to say that there is one best free antivirus software for 2026 that everyone could agree on. However, Bitdefender Antivirus Free has always been the one that offers the best combination of effectiveness, friendliness to users, and the least demanding of the computer’s resources. Avast Free Antivirus is a tempting second choice for those looking for more robust capabilities.
Your best bet for robust, long-term protection in 2026 and beyond is a mix of free antivirus software and basic security behaviours, including avoiding questionable links, regularly updating software, and using strong passwords.
