A viewer received a popup warning claiming her device had 120 viruses, which is a scam designed to prompt her to download a free antivirus app called "Total Cleaner." This alert is misleading and cannot scan the phone for viruses. The app has fake reviews, hidden costs, and privacy concerns, as it collects personal data. Most modern smartphones do not need traditional antivirus programs, and such popups are advertisements from free apps, misleading websites, or ad networks. To protect yourself, close the tab immediately, keep your device updated, and only download apps from official app stores after thorough research.

Check Point Research revealed a technique that uses the boot-time remediation driver BTR.sys, part of Windows Defender, to execute kernel-level operations on Windows systems from Windows 7 to Windows 11 25H2. This method does not exploit software vulnerabilities but leverages BTR.sys, which is designed to remove locked malware components. Researchers reverse-engineered its undocumented protocol, leading to the creation of a proof-of-concept tool, BTR_CLI, that can install the driver as a service without standard management protocols. Once operational, BTR.sys can delete or move files, modify registry entries, and remove security binaries, including parts of Defender, during a specific period when the file system is writable. To exploit this technique, an attacker needs administrator privileges, specifically SeLoadDriverPrivilege. Although Microsoft does not consider this a critical issue due to the requirement of pre-existing administrative access, it highlights a significant potential vulnerability. There have been no documented real-world attacks using this technique.

On July 31, 1996, Microsoft unveiled Windows NT 4.0 to its manufacturing partners. This release, codenamed Cairo, integrated the Windows 95 interface into a 32-bit enterprise OS and was the last version to support Alpha, MIPS, or PowerPC CPU architectures. The first public release of the NT line was Windows NT Server 3.1 in 1993, followed by versions 3.5 and 3.51 in 1994 and 1995, respectively. Windows NT 4.0 introduced features like My Computer and My Documents, as well as advanced components such as the cryptography API, DCOM, TAPI 2.0, and DirectX (v2). It had low minimum system requirements, recommending a CPU of 33 MHz or better, 32MB of RAM, SVGA graphics, and a 256 MB hard disk. NT 4.0 served as the foundation for Windows XP, which was released in 2001.
