Microsoft Pulls Post Saying Defender Covers Everyday Risk as Consumer Antivirus Market Tops $21.6 Billion

Summary
Microsoft quietly removed a Windows Learning Center page that said Microsoft Defender is sufficient for many Windows 11 users without extra antivirus software; the original link now redirects to the site home page.
The article offered no public explanation for the takedown, but the report points to possible pressure from third-party security vendors and potential antitrust threats tied to a consumer endpoint market estimated at $21.6 billion.
AV-Comparatives' February-May 2026 test gave Defender a 99.0% protection rate and no false positives, supporting the removed page's claim that built-in protection is adequate for most consumers.
OpenText data cited in the report put consumer PC infection rates at 3.07% in 2023-2024, with 37.6% of detected malware found in Downloads folders, suggesting user behavior drives many infections.
The report draws a line between home and work use: consumers may not need paid antivirus, while businesses still require broader endpoint security platforms beyond basic malware blocking.
