Safe Mode and Boot-Time Scans
When standard antivirus scans are insufficient, using Safe Mode and Boot-Time Scans enhances your chances of removing hidden viruses.
- Restart in Safe Mode: Safe Mode loads only essential system files, preventing malware from running. To enter Safe Mode:
- Windows: Restart and press F8 or hold Shift while clicking Restart, then select Safe Mode.
- Mac: Restart and hold Shift until the Apple logo appears.
- Run Antivirus Software in Safe Mode: Perform a full scan using your antivirus software while in Safe Mode. This method often disables malicious software that usually prevents the antivirus from functioning correctly.
- Boot-Time Scan with Avast: If using Avast and malware blocks scans, schedule a Boot-Time Scan through Safe Mode. This scan runs automatically before the operating system loads, improving detection and removal efficiency.
