phishing protection

Phishing protection on Windows covers both built-in and third-party defenses against credential theft and social engineering. Recent discussions highlight Microsoft's April 2026 Remote Desktop hardening, which adds warnings for unsigned or suspicious RDP files to block phishing attacks that exploit remote connections. Antivirus reviews show that Bitdefender Free and Microsoft Defender both offer strong phishing blocking, with Defender providing a capable baseline for many users. For businesses, practical guides emphasize multi-layered defenses including MFA and user training. Microsoft Teams is also gaining brand impersonation protection for calls. These sources collectively show that phishing protection spans RDP security, antivirus features, and communication platform safeguards.
