AI Is Changing Antivirus From File Matching to Behaviour-Based Malware Detection

Artificial intelligence is transforming malware detection by moving away from traditional file signature reliance to analyzing program actions. Antivirus software previously used signatures to identify known threats, but the rapid emergence of over 450,000 new malware samples daily complicates this method. Attackers now employ techniques like repacking and encryption to evade detection, prompting the need for machine-learning and behavioral techniques for better protection. Modern detection systems assess multiple characteristics of executable files, including their behavior, to identify potential threats, even if they lack recognized signatures. Microsoft's Project Ire exemplifies advanced detection capabilities, functioning as an automated malware analyst that evaluates unknown binaries based on their behavior. Additionally, modern endpoint-security products leverage cloud systems to analyze data from multiple devices, enhancing threat detection through shared intelligence. However, AI detection can still produce false positives and is susceptible to manipulation by attackers. Therefore, effective security systems require a combination of traditional measures, behavioral monitoring, machine learning, and human analysis to navigate complex threats.

Best Malware Removal Tools of 2026: Tested on Infected PC

A hands-on evaluation was conducted to assess the effectiveness of various malware removal tools by deliberately infecting a PC and running six different cleanup tools. The recommended steps for users suspecting malware infection include disconnecting from the internet, installing an on-demand scanner, removing detected threats, rebooting the system, and changing passwords. The top malware removal tools identified were: 1. Malwarebytes Free: Quick scan in 2 minutes and 20 seconds; complete removal with no remnants. 2. Bitdefender: Quick scan in 1 minute and 4 seconds; complete removal confirmed. 3. Norton 360: Quick scan in 58 seconds; effective for severely compromised devices. 4. Avast One Free: Quick scan in 1 minute and 12 seconds; complete removal with ongoing protection. 5. McAfee: Full system scan took 16 minutes and 47 seconds; complete removal but slower than others. 6. NordVPN Threat Protection Pro: Focuses on preventing reinfection, does not remove existing malware. Signs of infection include unexpected pop-ups, altered homepage settings, and sluggish performance. For Windows, Safe Mode with Networking is recommended for removal, while Mac users should use Activity Monitor to identify suspicious processes. Android users can utilize Safe Mode and Play Protect for scanning. A factory reset may be necessary if infections persist. Malwarebytes Free and Avast One Free are highlighted as effective free options for malware removal.

Best Android Antivirus Apps 2026: Tested and Ranked

Bitdefender Mobile Security is rated as the best antivirus app for Android in 2026, achieving a 100% detection rate, 0.5% battery drain, and unobtrusive operation. The evaluation compared five antivirus applications on a Galaxy S26 Ultra, assessing detection rates, battery drain, scan speed, and permissions. Other notable antivirus apps include Norton 360 for Mobile, which is recognized for its features; Avast Mobile Security, known for its free version; McAfee Mobile Security, which excels in scam call and text filtering; and NordVPN Threat Protection, praised for web and Wi-Fi security. Most users may not need an antivirus app due to built-in protections like Google Play Protect, which automatically scans apps. However, specific scenarios warrant the installation of an antivirus app, such as sideloading apps, receiving scam texts and calls, assisting relatives, conducting banking and shopping on mobile, and using public Wi-Fi. The top five antivirus apps tested are: 1. Bitdefender Mobile Security: 100% detection, 0.5% battery drain, 31-second scan time. 2. Norton 360 for Mobile: 99.9% detection, 0.9% battery drain, 24-second scan time. 3. Avast Mobile Security: 99.9% detection, 0.7% battery drain, 26-second scan time. 4. McAfee Mobile Security: 99.78% detection, 1.0% battery drain, 34-second scan time. 5. NordVPN Threat Protection: 95.60% detection of web threats, 0.2% battery drain. Battery consumption varied, with NordVPN being the lightest and McAfee the heaviest. Permissions requested by each app also varied significantly, with Bitdefender requiring the most extensive permissions. Users are advised to check for legitimate antivirus apps by verifying the developer, installation count, update history, lab participation, and permission requests. Free antivirus apps like Avast and AVG offer effective protection but may lack some features of paid versions. Users should be cautious of fake security apps that mimic legitimate ones. If malware is suspected, users can run scans with Google Play Protect or other anti-malware apps and follow specific steps to remove malware if detected.

ShieldBreak: New Windows Zero-Day Bypasses Microsoft’s RoguePlanet Patch

Chaotic Eclipse, a security researcher, has revealed a proof-of-concept (PoC) for a new vulnerability called ShieldBreak, which is a zero-day flaw in Microsoft Defender that bypasses the patch for the previously identified CVE-2026-50656 (RoguePlanet). This vulnerability could allow attackers to execute code at the SYSTEM level on affected Windows systems. Chaotic Eclipse tested the PoC on the latest versions of Windows 11 and Windows Server 2025, achieving a 100% success rate. Windows 10 and its server editions are not supported by the PoC but remain vulnerable. Microsoft had issued security updates for RoguePlanet, which has a CVSS score of 7.8, affecting the Malware Protection Engine and representing a local privilege escalation issue. Chaotic Eclipse has previously disclosed two other zero-day vulnerabilities, YellowKey and GreenPlasma, which affect BitLocker and the Windows Collaborative Translation Framework, respectively. Microsoft criticized the public disclosure of these vulnerabilities as irresponsible and emphasized the importance of Coordinated Vulnerability Disclosure.
