Best Antivirus for Windows 2026: 5 to Install, 1 to Avoid

A 2026 review ranks five paid Windows antivirus products and Microsoft Defender. Norton 360 tops the list, completing a full scan in 13 minutes 22 seconds and offering a robust firewall and 250 GB cloud backup.

NordVPN Threat Protection Pro provides full Windows protection for VPN subscribers. McAfee + offers unlimited device coverage but has the slowest scan.

How to reinstall Windows and give your PC a fresh start

Windows 11 and 10 now manage system cleanliness automatically, reducing the need for frequent reinstallations that were common with older versions like Windows 95 and XP. However, a fresh install remains useful when upgrading to Windows 11, clearing persistent junk, or simplifying system maintenance. Before reinstalling, users should back up data, create a disk clone, inventory installed programs, and deactivate software licenses that limit installations. These precautions ensure data recovery and a smoother post‑install setup. The guide outlines step‑by‑step preparation and execution for a secure reset.

💡 A clean reinstall can eliminate hidden registry clutter that slows performance, giving users a leaner, faster system without the hassle of manual cleanup.

Microsoft’s Patch Tuesday updates: Keeping up with the latest fixes

Microsoft’s September 2026 Patch Tuesday release addresses 963 CVEs, marking the largest security update of the year. The patch cycle includes fixes for two vulnerabilities already under active exploitation: CVE-2026-81963 in the Windows Update Stack and CVE-2026-85880 in Advanced Local Procedure Call. No flaws in this specific release were publicly disclosed prior to the patch. IT administrators are advised to prioritize immediate updates for Windows, Office, SQL Server, and developer tools, while scheduling standard releases for Exchange. This update follows a similarly heavy August cycle that resolved 751 CVEs, including an exploited elevation of privilege in the Windows WinSock driver. The July release also saw record-breaking activity, addressing 722 CVEs and two actively exploited flaws in Active Directory Federation Services and SharePoint Server. These consecutive high-volume releases underscore the persistent threat landscape facing enterprise environments.

💡 The sheer volume of critical fixes demands immediate triage to prevent lateral movement. Delaying deployment leaves exposed systems vulnerable to known, actively exploited attack vectors.
