There was a time when installing antivirus software was one of the first things people did after buying a new computer. In 2026, that is no longer the case for many users. Modern devices come equipped with built-in security features that are far more capable than those available a decade ago.
Windows includes Microsoft Defender, Apple has strengthened security across macOS and iOS, and Android devices benefit from Google's Play Protect and regular security updates. Meanwhile, cyber criminals have changed their methods.
Instead of relying solely on traditional computer viruses, they are increasingly using phishing emails, fake websites, scam text messages and social engineering to trick people into handing over sensitive information.
As a result, the question is no longer whether antivirus software can stop malware, but whether it is enough on its own. Cybersecurity experts say the answer depends on how you use your devices, the information you store on them, and whether you need extra security features beyond basic malware protection.
Built-in Protection Is Stronger Than Ever
The biggest reason antivirus software is no longer essential for everyone is the steady improvement in built-in security tools.
For Windows users, Microsoft Defender has evolved from a basic antivirus programme into a comprehensive security platform. It offers real-time malware protection, ransomware detection, firewall management and cloud-based threat intelligence, all without requiring an additional subscription.
Independent testing by AV-TEST has consistently awarded Microsoft Defender top marks for protection, performance and usability, placing it alongside many leading paid antivirus products.
Microsoft itself maintains that Defender provides enough protection for most home users. The company notes that many people only need additional security software if they want features such as identity theft monitoring, parental controls, password management or a virtual private network.
Viktor Bulanek, founder of Penetrify, an autonomous AI penetration testing company, agrees that built-in protection has reached the point where many consumers no longer need to pay for additional antivirus software.
'For most people the built-in protection is enough,' he said. 'Microsoft Defender has been in the same band as the paid suites in independent testing for years now.' Bulanek added that many people buying third-party antivirus are 'mostly buying a subscription to a feeling.'
Apple has also strengthened its security offering over the years. Macs now include Gatekeeper, which checks downloaded applications before they are opened, while XProtect scans for known malware in the background. Apple also uses app sandboxing and built-in malware removal tools to limit the damage if malicious software does make its way onto a device.
Although malware can target macOS, security researchers generally agree that Apple's layered approach provides robust protection for the average user. People who download software from trusted developers, keep macOS updated, and avoid suspicious websites are unlikely to encounter traditional malware.
The conversation around cybersecurity has also shifted. Roger Grimes, Data-Driven Defense Evangelist at KnowBe4 and a long-time cybersecurity author, argues that people have become the primary target for attackers. As he puts it, 'People are the biggest vulnerability.'
His point reflects a growing consensus across the cybersecurity industry that criminals increasingly succeed by manipulating users rather than bypassing security software. That is why experts now place as much emphasis on recognising scams as they do on installing antivirus software.
Mobile Security and When Paid Antivirus Still Makes Sense
The same trend can be seen on smartphones.
Apple's iPhone security relies on a tightly controlled App Store, application sandboxing and rapid security updates. These measures make traditional viruses relatively uncommon on iOS devices.
Android offers more flexibility, which also creates more opportunities for malicious applications. However, Google Play Protect automatically scans apps for known threats, while newer versions of Android include stronger privacy controls and regular security patches.
As long as users download apps from reputable sources and keep their devices updated, the built-in protections are sufficient for most people.
The bigger threat comes from online scams rather than malicious apps.
Bulanek said the biggest cyber risks today rarely involve traditional malware. 'Almost nobody I see getting hurt these days got hurt by a file,' he explained.
'They got phished, reused a password that turned up in a breach, approved a login prompt they did not understand, or installed something they genuinely wanted from a site that was not the real one.' He argued that antivirus software has limited value against those types of attacks, making good security habits far more important.
Cyber criminals impersonate banks, delivery companies, streaming services and even family members through convincing emails, text messages and messaging apps. They often attempt to steal passwords or persuade victims to authorise fraudulent payments instead of infecting devices with malware.
Jen Easterly, the former Director of the US Cybersecurity and Infrastructure Security Agency (CISA), has repeatedly argued that improving software security and basic cyber hygiene is more effective than relying on individual security products.
She has said, 'We don't actually have a cybersecurity problem; we have a software quality problem,' highlighting the importance of secure software, timely updates and strong security practices.
That message is echoed in CISA's public guidance, which recommends enabling multi-factor authentication, keeping devices updated, using strong passwords and learning to recognise phishing attempts as the most effective ways to stay safe online.
So, does that mean nobody should buy antivirus software anymore?
Not necessarily.
Third-party antivirus suites still offer benefits that go well beyond malware detection. Many include password managers, encrypted cloud backups, identity theft monitoring, dark web monitoring, parental controls, VPN services and protection for multiple devices under a single subscription.
For families managing several computers, tablets and smartphones, these bundled features can provide added convenience and peace of mind.
Paid antivirus software may also be worthwhile for people who frequently download files from unfamiliar websites, work with sensitive business information or simply want extra layers of protection against emerging threats.
Independent testing continues to show that premium products from companies including Bitdefender, Norton and ESET perform exceptionally well at detecting malware.
However, the performance gap between these products and Microsoft Defender has narrowed considerably in recent years, making the decision less about malware detection and more about the additional services included.
For the average home user, the reality in 2026 is straightforward. If you use Windows with Microsoft Defender enabled, keep your operating system updated, install software only from trusted sources, enable multi-factor authentication, and think carefully before clicking unfamiliar links, buying antivirus software is no longer a necessity.
Modern cybersecurity is no longer defined by computer viruses alone. The greatest risks now come from deception, impersonation and stolen credentials. Built-in security tools have become remarkably capable, but they cannot stop someone from voluntarily handing over a password or approving a fraudulent payment.
Bulanek believes paid antivirus remains valuable in business environments, although not necessarily because it detects more malware. 'A business needs central visibility, logs and something to show an auditor,' he said. 'A single home user has no auditor and should not pay as if they did.'
That is why cybersecurity experts increasingly agree that the best defence combines strong built-in protection with good online habits. For many people, that means the antivirus software already installed on their device is enough. The most important upgrade is not another application, but a more cautious approach to life online.
