Here’s What Actually Happens When Antivirus Software Scans Your PC

Interactions with antivirus software occur during installation and when issues arise, while the software operates quietly in the background. Modern antivirus solutions continuously monitor for threats using various detection methods, including real-time scanning, which actively scrutinizes files as they are downloaded or accessed. The signature database is essential for identifying malware by comparing files against known signatures, but it can only detect documented threats. Heuristic detection and behavioral analysis help catch unknown malware by evaluating suspicious characteristics and monitoring file actions during execution. Sandboxing allows suspicious files to run in a controlled environment, logging their behavior to determine if they are malicious. Quarantine neutralizes threats by locking files in a secure location, allowing users to review them before deletion. Full scans are resource-intensive and can slow down system performance, while real-time scanning is less demanding. Users can schedule scans during idle times, exclude trusted folders, or consider cloud-based solutions to mitigate performance impacts.

Retro gaming fans are the new target for fake GitHub malware

Retro gaming enthusiasts should be cautious when exploring GitHub projects for tools or plugins, as cybercriminals may disguise malware as homebrew software. A specific incident involved a project called EQVita, which pretended to be a free audio tool for PlayStation Vita but actually contained Windows malware. The downloaded file included three files: Launch.bat, luajit.exe, and x64.txt, with the latter concealing a hidden script that connected to the attacker's server upon execution. This scam is part of a broader trend where counterfeit GitHub repositories distribute SmartLoader malware, which retrieves additional malicious software aimed at stealing passwords and cryptocurrency wallets. The PS Vita community, despite the console's production ceasing, remains active in modding, making it a target for attackers. Legitimate plugins typically come in Vita-compatible formats, while fake ones may feature polished marketing materials and AI-generated descriptions. Users are advised to verify sources, be cautious of suspicious downloads, and utilize security tools like Malwarebytes. If someone has executed the malicious EQVitav1.3.zip file, they should conduct a malware scan, change important passwords, and monitor accounts for unauthorized access. Indicators of compromise include the domains https://github.com/Voistace/EQVita and https://voistace.github.io, and the IP address 85.137.52.21.

Microsoft released the Windows 11 Secure Boot update for all PCs, how to verify yours

Microsoft has expanded the rollout of the Secure Boot 2023 certificate update to more Windows 11 and Windows 10 devices with the June 2026 Patch Tuesday update (KB5094126). This update aims to ensure that most supported consumer PCs are classified as high confidence, meaning necessary certificates are either installed or will be applied automatically. Secure Boot is a firmware security feature that verifies the software attempting to load during the startup process, blocking unauthorized software. The certificates supporting Secure Boot, issued in 2011, are expiring in stages starting June 24, 2026, prompting Microsoft to deploy replacement certificates. Most home users do not need to take manual action as the updates will occur automatically via Windows Update. Users can check their Secure Boot certificate status in the Windows Security app. A yellow warning indicates pending compatibility data, while a red alert suggests a firmware incompatibility requiring a BIOS update. Multiple reboots during the update process are normal, and a new SecureBoot folder in Windows is for staging cryptographic files. Older PCs may experience longer update times, and some may not receive updates due to firmware issues. HP users should check for BIOS updates if encountering BitLocker recovery loops. IT administrators should monitor device classifications and manually initiate updates for devices not in the high confidence category. Devices with Secure Boot disabled cannot receive updates, leaving them vulnerable. The expiration of the Microsoft Corporation KEK CA 2011 certificate on June 24 does not immediately affect device functionality, but it limits Microsoft's ability to sign new bootkit blacklist updates.

Troubleshoot common Windows 11 Pro security alerts and what to do next

Windows 11 Pro includes a suite of security features under Windows Security, which continuously protects the PC. Common security alerts include: 1. "Turn on virus protection" or "Real-time protection is off" alerts: These occur after installing or removing a third-party antivirus. To restore protection, open Windows Security, select Turn on in the Virus & threat protection section, and confirm. 2. "Threat found" or "Threat found - action needed" alerts: Indicate that Windows Defender has detected a potential threat. To manage these, open Windows Security, navigate to Virus & threat protection, click on Protection history, select Threat blocked, and use the Actions dropdown to quarantine or allow the file. 3. "Threat quarantined" or "Threat blocked" alerts: A Threat quarantined alert means a file is isolated for review, while a Threat blocked alert indicates successful removal by Defender. Investigate how the threat entered the system. 4. SmartScreen alerts: SmartScreen protects against malicious websites and downloads. If a threat is identified, a red warning page appears. Users can report the site as safe or proceed at their own risk. Blocked downloads can be managed in Edge's Downloads menu. 5. "This app has been blocked" alerts: Smart App Control prevents the installation of untrusted applications. Disabling this feature should only be done if the application is deemed safe. Settings can be found under Windows Security > App & browser control > Smart App Control settings.

Microsoft reveals Windows 11 will bulk delete files at least 30% faster, and it’s only the start

Microsoft is working on enhancements for File Explorer on Windows 11 to improve speed and efficiency, particularly in batch file deletions. Internal testing is underway for a performance boost, with potential speed increases of over 30% for bulk deletions following an upcoming update. Other file operations, such as transfers and copies, are also set to become faster. The company aims to improve launch times, reduce flickering, and eliminate distracting flashes in dark mode. Users have already noticed faster launch times and better handling of file names and paths. Microsoft is testing a preloading feature for File Explorer and plans to revamp the right-click menu for faster loading and a streamlined appearance. Additionally, the company is exploring ways to minimize File Explorer’s memory footprint and modernize legacy elements. Microsoft plans to introduce up to 19 new features by 2026, including a movable taskbar and a customizable Start menu.
