How to Scan Your Computer for Malware

Step by step

1. 1 min

   Update your operating system

   Before scanning, ensure your security definitions are current. On Windows, navigate to Settings > Windows Update > Check for updates. On macOS, go to System Settings > General > Software Update to install the latest security patches.

   Note: Outdated software often lacks the signatures required to detect modern threats.

   Run a scan on macOS

   macOS utilizes XProtect for real-time protection. To verify system integrity, run a check using Terminal by typing 'tccutil reset All' followed by a restart. For deep scanning, use a trusted third-party security utility specifically designed for macOS, such as Malwarebytes for Mac.

   Note: Avoid using multiple active antivirus engines simultaneously to prevent system conflicts.

   Analyze detection results

   Once the scan completes, the interface will display a list of detected threats. Carefully review each item to ensure it is not a false positive. Select the recommended action, typically labeled as Quarantine or Remove, for all confirmed malicious files.

   Note: If a file is flagged but you believe it is safe, verify the file path before choosing to ignore it.

   Clear temporary files

   Many malware strains hide in temporary directories. After removing threats, empty the Recycle Bin or Trash to ensure deleted malicious components are permanently purged from your storage volume.

   Note: Perform a system restart immediately after clearing the bin to finalize the removal process.

   Verify browser security

   Malware often installs unauthorized extensions. Open your browser settings, navigate to Extensions, and remove any items you do not recognize. Reset your browser startup page to your preferred default.

   Note: Malicious extensions are the most common cause of persistent browser redirects.
