When Malwarebytes scan gets stuck, it means the scanning process freezes at a certain percentage or stops progressing completely. This can happen during a Quick Scan, Full Scan, or custom scan. Since scanning is essential for detecting malware, ransomware, and other hidden threats, a stuck scan should be fixed as soon as possible.
In most cases, this issue is temporary and caused by system overload, software conflicts, or corrupted files. This guide explains why scans get stuck and how to fix them step by step.
Why Malwarebytes Scan Gets Stuck
There are several common reasons why Malwarebytes scans may freeze:
- System overload or low memory
- Conflicts with other antivirus software
- Corrupted scan cache or temporary files
- Large or damaged files being scanned
- Outdated Malwarebytes version
- Background processes interfering with scanning
- Stuck or interrupted previous scan
Identifying the cause helps you fix the issue more effectively.
Basic Fixes to Try First
Start with simple troubleshooting steps:
1. Wait for a Few Minutes
Sometimes the scan appears stuck but is still processing large files.
2. Restart Your Computer
A restart clears temporary system errors.
3. Restart Malwarebytes
Close the application completely and reopen it.
4. Run as Administrator
Right-click Malwarebytes and select “Run as administrator”.
These basic steps often resolve minor scan freezes.
Fix 1: End Stuck Scan Processes
If the scan is completely frozen:
- Open Task Manager
- End all Malwarebytes-related processes
- Restart the application
- Start a new scan
This clears the stuck scanning session.
Fix 2: Check System Performance
Low system resources can cause scan freezing:
- Close heavy applications and browser tabs
- Free up RAM and storage space
- Restart your system if needed
A slow system can interrupt scanning progress.
Fix 3: Disable Conflicting Antivirus Software
Other security programs may interfere:
- Temporarily disable antivirus or firewall
- Restart Malwarebytes
- Start scan again
Running multiple antivirus tools can lead to scan conflicts.
Fix 4: Update Malwarebytes
An outdated version may cause scanning issues:
- Check for available updates
- Install the latest version
- Restart your computer
Updates often fix scan-related bugs.
Fix 5: Restart Malwarebytes Services
If background services are stuck:
- Open system services panel
- Locate Malwarebytes services
- Restart them manually
- Try scanning again
This refreshes the scanning engine.
Fix 6: Repair or Reinstall Malwarebytes
If the issue continues:
- Repair the installation if possible
- Or uninstall and reinstall Malwarebytes
- Restart your system afterward
This removes corrupted files causing scan issues.
How to Prevent Scan Freezing
To avoid future scan issues:
- Keep Malwarebytes updated
- Avoid running multiple antivirus programs
- Close unnecessary applications before scanning
- Ensure enough system memory is available
- Restart your system regularly
These habits help maintain smooth scanning performance.
Conclusion
If Malwarebytes scan gets stuck, the issue is usually caused by system overload, software conflicts, or temporary glitches. Most problems can be fixed by restarting the system, closing background processes, or updating the application.
In rare cases, reinstalling Malwarebytes may be required. Once resolved, scans will run smoothly and continue protecting your device from malware, ransomware, and other security threats.
