When Malwarebytes is not working on Windows 10, it can show different problems such as not opening, freezing, crashing, failing to scan, or real-time protection not working. Since Windows 10 is still widely used, these issues are usually caused by system conflicts, outdated software, or corrupted files rather than major system failures.
This guide explains why Malwarebytes may not work properly on Windows 10 and how to fix it step by step.
Why Malwarebytes Is Not Working on Windows 10
There are several common reasons why Malwarebytes may stop working on Windows 10:
- Windows updates causing compatibility issues
- Corrupted or incomplete installation
- Conflicts with Windows Defender or other antivirus programs
- Outdated Malwarebytes version
- Disabled background services
- Low system memory or performance issues
- Damaged system files in Windows 10
Understanding the cause helps you choose the correct fix.
Basic Fixes to Try First
Start with simple troubleshooting steps:
1. Restart Your Computer
A restart fixes temporary glitches caused by Windows processes.
2. Open Malwarebytes Again
Try launching the program after rebooting the system.
3. Run as Administrator
Right-click Malwarebytes and select “Run as administrator”.
4. Close Background Apps
Too many running programs can slow down or block security software.
These basic steps often fix minor issues quickly.
Fix 1: Check Windows Defender Conflicts
Windows Defender can sometimes interfere:
- Open Windows Security settings
- Temporarily disable real-time protection
- Check if Malwarebytes starts working
- Re-enable protection after testing
Conflicts between security tools are common on Windows 10.
Fix 2: Update Malwarebytes and Windows 10
Outdated software may cause compatibility issues:
- Install the latest updates for Malwarebytes
- Run Windows Update and install pending updates
- Restart your computer
Updates improve stability and fix bugs.
Fix 3: Repair Malwarebytes Installation
If files are corrupted:
- Go to installed apps
- Select Malwarebytes
- Choose repair option if available
- Restart your system
Repairing restores missing or broken components.
Fix 4: Restart Malwarebytes Services
If services are not running:
- Open Services in Windows 10
- Find Malwarebytes services
- Restart them manually
- Set startup type to automatic
Without services, the program cannot function properly.
Fix 5: Check System Performance
Low system resources may cause issues:
- Close heavy applications and browser tabs
- Free up RAM and storage
- Restart your PC
Windows 10 performance issues can affect Malwarebytes operation.
Fix 6: Reinstall Malwarebytes (Last Option)
If nothing else works:
- Uninstall Malwarebytes
- Restart your computer
- Install a fresh copy
- Sign in and activate your subscription
A clean reinstall fixes deep system conflicts.
How to Prevent Issues on Windows 10
To avoid future problems:
- Keep Windows 10 updated regularly
- Keep Malwarebytes updated
- Avoid running multiple antivirus programs
- Restart your system often
- Maintain enough free storage and memory
These habits help ensure smooth performance.
Conclusion
If Malwarebytes is not working on Windows 10, the issue is usually caused by software conflicts, outdated versions, or system glitches. Most problems can be fixed by restarting the system, updating software, or repairing the installation.
In rare cases, a reinstall may be required. Once fixed, Malwarebytes will run properly on Windows 10 and continue protecting your system from malware, ransomware, and other threats.
