Microsoft will disable the NTLM authentication protocol by default in the next major Windows Server release and associated Windows client versions. NTLM, introduced in 1993, has been vulnerable to various cyberattacks, including NTLM relay and pass-the-hash attacks. The transition plan includes three phases: enhanced auditing tools in Windows 11 24H2 and Windows Server 2025, new features like IAKerb and a Local Key Distribution Center in late 2026, and eventually disabling network NTLM by default in future releases. NTLM will remain in the operating system but will not be used automatically. Microsoft deprecated NTLM authentication in July 2024 and has encouraged developers to transition to Kerberos or Negotiation authentication.

Virus protection is essential in the digital landscape due to threats like ransomware, phishing, spyware, and trojans that can compromise personal data and financial security. Cybercriminals continuously innovate, leading to potential malware infections that can steal sensitive information, lock files for ransom, or degrade device performance. Windows includes Microsoft Defender Antivirus, which provides real-time protection, automatic updates, cloud-based scanning, and firewall features. macOS offers built-in security tools such as XProtect, Gatekeeper, and the Malware Removal Tool, alongside regular updates. Linux distributions like Ubuntu are designed with security in mind, featuring regular patches, AppArmor, and optional antivirus tools. Key features to look for in antivirus software include real-time scanning, firewall protection, web protection, email scanning, automatic updates, and parental controls. While built-in solutions are often sufficient for everyday users, advanced users may benefit from third-party antivirus software. Best practices for maintaining cyber hygiene include keeping software updated, avoiding unverified applications, using strong passwords, enabling two-factor authentication, and regularly backing up data.
