Is paid antivirus actually a waste of money for your PC in 2026?

Windows has evolved from being a target for malware to having robust built-in protection, particularly through Microsoft Defender Antivirus, which has improved from a score of 0.5 in 2015 to a perfect score of six in 2026, detecting 100% of threats. Microsoft Defender operates seamlessly in the background, automatically scanning files and applications. Third-party antivirus solutions, while offering additional features like anti-scam tools and VPNs, may not be necessary for all users, especially since many browsers have built-in protections. Users are encouraged to reassess the necessity of paid antivirus subscriptions, as free versions can be intrusive and may lead to conflicts with Defender. Performance tests indicate that third-party antivirus solutions can impact game performance, with Malwarebytes Premium showing a notable reduction in frame rates during scans. For most users, Windows' built-in protection is likely sufficient unless specific additional features are needed.

Microsoft Wants to Protect Your Linux Desktop with Defender

Microsoft has expanded its Defender security software to Linux desktop environments, currently in public preview. Microsoft Defender for Endpoint is designed for organizations using Linux workstations and aims to enhance security for developers who interact with sensitive resources. Key features include real-time antivirus protection, endpoint detection and response, threat investigation, vulnerability management, and centralized security monitoring. The software uses the same deployment packages and installation methods as those for Linux servers, supporting distributions like Ubuntu LTS, Debian, Fedora, Red Hat Enterprise Linux, openSUSE Leap, SUSE Linux Enterprise, Rocky Linux, and AlmaLinux. Compatibility with desktop environments is based on the underlying distribution and kernel. The software identifies devices by assessing operating system metadata, and if it cannot classify a machine as a workstation, it defaults to identifying it as a server. This development follows the introduction of Defender for Linux servers in 2020. Organizations need a Microsoft Defender for Endpoint subscription and must meet Linux system requirements to use the software.

How to protect your PC from malware

Malware, short for "malicious software," is designed to gain unauthorized access to computers or networks for purposes such as data theft and surveillance. It can be introduced through disguised software or deceptive links. To protect against malware, it is essential to install antivirus software, scan external drives before connecting them, be cautious about downloads, avoid suspicious websites and emails, update applications regularly, enable Tamper Protection on Windows, minimize file sharing, enable Firewall protection, watch out for phishing attacks, and back up data regularly. The future of malware protection may involve leveraging artificial intelligence and machine learning to enhance detection and analysis of threats.

Windows 11 promises to clean up bloat, but disabling its own features is the only thing that works

Upon installing Windows 11, users encounter numerous pre-installed applications, promotional tiles, and cloud-connected features. These apps are organized in two phases: system-level staging and user-specific activation. The AppX Deployment Service registers these apps for users, creating app data folders. Microsoft also embeds custom app shortcuts and trial software into the Start menu using LayoutModification.json. During setup, Microsoft's Consumer Experience feature connects to cloud servers, downloading app placeholders that are pinned to the Start menu. Local search is integrated with Bing by default, sending requests for suggestions and promoted content. To clean up Windows 11, users can uninstall non-essential applications through Settings, but this only removes them from the user profile. To permanently eliminate app templates, PowerShell commands can be used. Users can disable promotional content in Settings under Personalization and Privacy & Security. To sever Bing integration from search, modifications in the registry editor are required. The Task Manager can help manage startup applications, allowing users to disable non-essential third-party apps. While removing unnecessary components can improve performance, essential packages like Edge WebView2 runtime, Microsoft Defender, and the Microsoft Store should be retained to avoid system errors. Regular maintenance is necessary, as Windows updates may reinstall previously removed apps.

VPN threat protection vs. dedicated antivirus: Are VPNs really enough?

Many VPN providers are now offering additional security features such as malware detection, malicious link checkers, and ad blockers, alongside their primary function of encrypting internet traffic. Notable VPNs like NordVPN and Surfshark have integrated real-time malware protection, with NordVPN becoming the first VPN to receive certification as a reliable anti-phishing tool in 2024. Surfshark's Surfshark One package offers comprehensive real-time protection from viruses and malware. Other VPNs, such as Avira and CyberGhost, utilize shared infrastructures for antivirus capabilities, which can lead to delays in updates and inconsistent platform support. Microsoft Defender has improved significantly, blocking 95.5% of live threats according to AV-Comparatives, while Apple employs multiple defenses in macOS, including Gatekeeper and XProtect, to manage malware threats. Avast Free Antivirus has achieved a perfect 100% block rate in recent testing but comes with limitations compared to paid antivirus suites like Norton 360 Deluxe and Bitdefender Total Security, which offer additional features such as password managers and identity monitoring. A layered approach to digital security, combining a VPN, free antivirus, and built-in OS-level security, is recommended for effective protection. Relying solely on one layer leaves potential gaps, as a VPN cannot detect existing malware, and free antivirus solutions may lack advanced features. Users managing sensitive data or frequent financial transactions should consider investing in premium antivirus suites for enhanced security.

Antivirus: Do you still need it?

Purchasing antivirus software is often seen as necessary but can be frustrating, especially with built-in security features available on most computers. Windows includes Microsoft Defender Antivirus, which has been independently tested and scored well for protection, performance, and usability. Mac users have XProtect for malware detection. Users should verify that their existing protection is enabled and up-to-date before considering a subscription. Antivirus programs combat various types of malware, using methods like signature scanning and heuristic analysis, but they are not infallible. Research on antivirus effectiveness varies, with scores reflecting different criteria and not universally applicable detection rates. Subscriptions may be worthwhile if they offer specific features, but users should be cautious about renewal prices and unnecessary multiple installations. Maintaining updated software and practicing good security habits are essential for protection. For everyday use, built-in protection is often sufficient unless additional benefits justify the cost of extra software.
