virus scan is mislukt melding hoe los ik dit op in windows 11

If you are encountering a "virus scan failed" message in Windows 11, there are several steps you can take to troubleshoot and resolve the issue:

1. Check for Updates: Ensure that your Windows 11 and Microsoft Defender Antivirus are up to date. Updates can fix bugs and improve performance.
2. Restart Your Device: Sometimes, simply restarting your computer can resolve temporary issues that may be causing the scan to fail.
3. Run a Different Scan: Try running a quick scan instead of a full scan. You can do this through the Windows Security app.
4. Check for Conflicts with Other Software: If you have other antivirus software installed, it may conflict with Microsoft Defender. Consider disabling or uninstalling other antivirus programs to see if that resolves the issue.
5. Review Event Logs: Use the Event Viewer to check for any error messages related to the scan. Look for events that might indicate why the scan was canceled or failed.
6. Power Settings: Ensure your device is plugged in during the scan. If your device is running on battery, it may stop the scan to save power.
7. Scan for Malware: If the issue persists, consider using the Microsoft Safety Scanner to check for malware that may be affecting the scanning process. You can download it and run a scan to remove any threats.
8. Check Scheduled Scans: If you have scheduled scans, ensure they are set up correctly and not conflicting with other tasks.

If these steps do not resolve the issue, you may need to consult the Microsoft support documentation for further assistance.

De beste optie is om eerst een volledige scan uit te voeren met de Microsoft Safety Scanner om te controleren of er malware op uw pc aanwezig is, en vervolgens te testen of een normale scan succesvol wordt afgerond.
