Do You Really Need Antivirus on Windows 11? Probably Not—Here’s Why

Windows 11 has robust built-in security features that may reduce the need for third-party antivirus software. Windows Security now offers comprehensive protection, including real-time malware detection, firewall protection, SmartScreen alerts, hardware-level security, account monitoring, and system health reports. According to AV-TEST results from January and February 2025, Microsoft Defender Antivirus scored 6.0/6.0 in protection, performance, and usability, effectively stopping advanced malware and phishing attempts with minimal system resource usage. Users of Microsoft Edge benefit from SmartScreen filtering, while those using other browsers receive system notifications for network protection. Basic digital hygiene practices, such as avoiding suspicious downloads and keeping software updated, are crucial for security. Third-party antivirus solutions may offer additional features but can lead to performance issues and privacy concerns. For casual users who maintain their systems and practice safe browsing, Windows Security is generally sufficient, while those handling sensitive information or needing advanced features may consider premium antivirus options.

Your Android phone will soon warn you about that sketchy app sneakily changing icons

Google Play Protect is set to enhance its security features to better defend against malicious applications. The upcoming update will include the ability to detect changes in app icons, alerting users when an app alters its icon, a tactic used by malicious developers. Additionally, Google Play Protect will improve its on-device malware detection capabilities by implementing new rules to identify specific text or binary patterns associated with known malware families. These enhancements aim to provide users with timely alerts before installing potentially harmful applications, significantly reducing the risk of malware. The new icon detection feature will roll out in the coming months, initially available on the Pixel 6 series and select devices from other manufacturers. The on-device rules will be updated regularly to address emerging threats, and the enhanced malware scanning capability will be accessible to all Android users with Google Play Services.

Database performance analysis using pg_profile and pgpro_pwr

pgpro_pwr is a database workload monitoring tool for database administrators (DBAs) to identify resource-demanding operations. It was launched in 2017 as pg_profile by Andrey Zubkov, who moved from being a DBA to an engineer at Postgres Professional. pg_profile is compatible with open-source PostgreSQL and has been integrated into PostgreSQL 17 as of 2024, while pgpro_pwr offers advanced statistical insights and is included in Postgres Pro releases. Both tools monitor database workload metrics through continuously incrementing counters, capturing values at intervals and archiving differences. They do not provide alerting capabilities but are useful for assessing system stability, analyzing load testing outcomes, and identifying system-intensive activities. The tools consist of repository tables, data collection functions, reporting functions, and service tables. To use them, one must install the extension, configure roles, and set up parameters. Reports can be generated for workload statistics over time and comparisons between different time intervals. Examples of report types include wait event statistics and advanced vacuum statistics. Future plans include submitting a patch to introduce vacuum statistics to vanilla PostgreSQL.

Hackers Using Windows Remote Management to Stealthily Navigate Active Directory Network

Threat actors are exploiting Windows Remote Management (WinRM) to navigate through Active Directory environments stealthily, allowing them to bypass detection systems, escalate privileges, and deploy malicious payloads. WinRM operates on HTTP port 5985 and HTTPS port 5986, enabling remote command execution and management tasks. Attackers can gain access through compromised credentials and use WinRM-enabled PowerShell commands for reconnaissance, deploying payloads while evading detection. The attack chain includes initial access, reconnaissance, payload deployment, persistence, and lateral movement, often utilizing techniques that obfuscate malicious activities. Detecting such attacks is challenging due to the use of built-in Windows functionalities and encrypted channels. Recommended mitigation strategies include monitoring for unusual activity, restricting WinRM access, enforcing credential hygiene, and implementing advanced monitoring solutions.
