The landscape of computer security has changed significantly over the past two decades. In 2026, antivirus protection remains important, but the need for separate third-party programs has decreased for many users due to the built-in Microsoft Defender in Windows 11, which is activated by default and effectively blocks 100% of common malware samples according to independent testing by AV-TEST. Windows 11 also includes additional protective features like SmartScreen and a robust Firewall. While dedicated security suites from companies like Norton and Bitdefender offer advanced functionalities, many users may find adequate protection with the built-in tools. Research from AV-Comparatives indicates that performance varies among security programs, particularly against real-world attacks. Phishing attacks accounted for approximately 60% of initial access points in incidents examined by the ENISA Threat Landscape report from 2025, highlighting that user behavior is a significant vulnerability. Modern web browsers and operating systems have enhanced their security measures, with Google Chrome, Microsoft Edge, macOS, and Android incorporating features to protect users from harmful websites and downloads. For the average Windows 11 user who keeps their system updated and practices safe browsing, built-in protection is generally sufficient, though paid antivirus options can provide additional tools.

A viewer received a popup warning claiming her device had 120 viruses, which is a scam designed to prompt her to download a free antivirus app called "Total Cleaner." This alert is misleading and cannot scan the phone for viruses. The app has fake reviews, hidden costs, and privacy concerns, as it collects personal data. Most modern smartphones do not need traditional antivirus programs, and such popups are advertisements from free apps, misleading websites, or ad networks. To protect yourself, close the tab immediately, keep your device updated, and only download apps from official app stores after thorough research.
