Best Antivirus for Mac 2026: Real Test Results and Ranking

Bitdefender Antivirus for Mac is the leading antivirus solution for Mac users in 2026, particularly effective on Apple Silicon and against live macOS threats. It achieved the highest malware detection rates, the fewest false alarms, and minimal impact on startup time. Other notable antivirus options include Norton 360 for Mac, Avast One for Mac, NordVPN Threat Protection Pro, McAfee Total Protection for Mac, and Malwarebytes for Mac. Each antivirus was tested on a MacBook Air against various malware, adware, and phishing threats, focusing on real-time protection, adware removal, and system performance impact. macOS includes built-in protections like XProtect, Gatekeeper, System Integrity Protection, app sandboxing, and Lockdown Mode, which provide a solid defense for users who only install software from the App Store.

Common threats for Mac users include adware, infostealers, and malvertising. The rankings of antivirus solutions were based on AV-TEST results, malware tests, system impact, and unique features. Bitdefender received a perfect score at AV-TEST and demonstrated 99.9% malware detection with only one false alarm.

Permanently disable Microsoft’s hidden tracker on all Windows 11 versions with this script

Microsoft's Global Device Identifier (GDID) is an internal marker that uniquely identifies each Windows installation across Microsoft services. It is a persistent device-level identifier that remains constant across supported services, and there is no option to disable or regenerate it manually. Windscribe has developed a free utility called deGDID to permanently remove the GDID from Windows systems and prevent its recreation. This tool operates by blocking Microsoft registration pathways and wiping local GDID-related states without altering system files. While it can remove the GDID from the local system, it cannot erase historical records linked to the device. Windscribe provides instructions for using the tool, which is compatible with Windows 10 version 22H2 and all versions of Windows 11 from 21H2 to 25H2. Users should be aware that disabling GDID generation may impact Microsoft services that rely on device identification, but the tool includes an undo feature to revert changes.

Your Android Phone Can Now Automatically Back Up Documents – Here’s How

Google Play Services version 26.26 has introduced a new backup feature for Android users that automatically backs up documents in various formats (.DOC, .PPT, .XLS, .PDF) from devices to Google Drive. This feature can be activated through Settings > Accounts and backup > Google Backup settings, where a new Documents category will appear. Backed-up documents will be stored in a folder named Android backups within Google Drive, but users should monitor their storage space as this will utilize their cloud storage. Alternative backup methods include using manufacturer-specific features or third-party apps like Syncthing.

This free Windows 11 tool can rescue your PC when things go wrong

System Restore is a recovery feature in Windows that allows users to revert their systems to a previous state by creating snapshots of the current configuration. It captures crucial system components such as Windows system files, Registry settings, device drivers, and installed applications, but does not back up personal files. Windows automatically generates restore points during significant events or after a week without new points, and users can manually create them before making substantial changes. Restore points occupy hard drive space, and the oldest points are deleted when storage is full. To use System Restore, users can configure it in the System Properties window, create restore points, view and select restore points, preview changes, and initiate the restoration process. After restoration, the PC reboots, and users should check if issues are resolved.

Why Does Windows Explorer Use So Much Memory?

A user on Reddit reported that Windows Explorer was using over 21GB of memory, which can cause performance issues on systems with less than 8GB of RAM. One cause of excessive memory consumption is third-party shell extensions, which can be identified by booting into Safe Mode. A tool called ShellExView can help locate problematic extensions. To create a system restore point, users can press Win + R, type systempropertiesprotection.exe, click Create, enter a description, and click Create. Windows Explorer may also retain large caches of temporary data, leading to high memory usage. To clear temporary files, users can press Win + I, navigate to System > Storage > Temporary files, check the relevant boxes, and click Remove files. They can also manually clean the thumbnail and icon cache by deleting specific files in the %localappdata% directory. Corrupted system files can contribute to high memory usage, and users can run DISM and SFC tools to repair these files by accessing the Terminal (admin) and executing the commands DISM.exe /Online /Cleanup-image /Restorehealth and sfc /scannow.

The 200GB catch hiding in Windows 11’s new recovery feature

Microsoft has introduced point-in-time restore for Windows 11 users, enhancing the traditional System Restore. This new recovery tool allows users to recover their PCs from software issues, problematic drivers, or faulty updates, even when Windows won’t boot. It uses the Volume Shadow Copy Service (VSS) to automatically generate restore points every 24 hours, which include both system and user files, unlike System Restore. Point-in-time restore manages storage by deleting restore points after 72 hours and integrates seamlessly into Windows Settings, being activated by default for volumes over 200GB. Users with smaller volumes must activate it manually. It also incorporates Reserved Storage to ensure restore points do not consume regular disk space. The feature is available on Windows 11 Home and Pro editions with the installation of the optional Preview Update KB5095093. Users can access point-in-time restore through Windows Settings under System > Recovery, and initiate recovery via the Windows Recovery Environment (Windows RE).

Windows 11 has more recovery options than ever, and here’s exactly when I would use each one to fix a broken PC

Microsoft has enhanced Windows 11 with various recovery tools that allow users to address system issues without needing to perform a complete reinstall. Key features include: - Reset This PC: Offers two options: "Keep my files" (reinstalls Windows while retaining personal files) and "Remove everything" (wipes the computer before reinstalling). Users can choose between a Local reinstall or Cloud download. - Cloud Rebuild: Accessible via the Windows Recovery Environment (WinRE), it reformats the OS partition, downloads a fresh Windows image, and restores the original setup without relying on local recovery images. - Go Back (Rollback): Allows users to revert to a previous installation after an upgrade if issues arise, utilizing the Windows.old folder, but is time-sensitive (files purged after about ten days). - Uninstall Updates: Enables users to remove recent updates that may cause problems without a full system reset. - System Restore: Creates restore points to revert to a stable state without affecting personal files. - Startup Repair: A tool in WinRE that scans for and fixes common startup issues. - Safe Mode: Starts Windows with essential drivers and services to troubleshoot problems. - Quick Machine Recovery: Automatically connects to Microsoft's recovery service to download fixes if Windows fails to start due to a faulty update or driver. - Point-in-Time Restore: Automatically reverts the system to a previous working state when updates fail. Other tools include the Windows Recovery Environment (WinRE), Recovery Drive for bootable USB access, Command Prompt, Startup Settings, and the Windows Backup app for restoring settings and files. The legacy Backup and Restore (Windows 7) tool is still available for creating backups and full system images.

Can Chromebooks Get Viruses? How to Protect Your Device

Chromebooks are designed with robust security features, including sandboxing, Verified Boot, automatic updates, data encryption, and Recovery Mode, which collectively reduce the risk of malware infections. However, they are still vulnerable to threats such as malicious Chrome extensions, scam Android apps from third-party stores, phishing attacks, and risks associated with using Developer Mode and cloud storage. Users can identify potential malware through signs like slow performance, unexpected pop-ups, and unusual battery drain. To remove malware, users should eliminate suspicious extensions, uninstall dubious apps, run antivirus scans, enable Google Play Protect, or perform a Powerwash to reset the device. To protect their Chromebooks, users should avoid Developer Mode, check app permissions, use two-factor authentication, verify website URLs, and use a VPN on public Wi-Fi.
