Quick Answer
procmon64.exe is safe. It is Sysinternals' 64-bit Process Monitor, used for real-time monitoring of file system, registry, and process activity on Windows.
Is it a Virus?
NO - Safe
Must be in C:\Sysinternals\Process Monitor\Procmon64.exe
Can I Disable?
YES - It will stop capturing events
Use to monitor system activity in real time; closing stops data capture
What is Procmon64.exe?
procmon64 is the 64-bit executable of Sysinternals Process Monitor. It provides real-time, low-level visibility into file system, registry, event traces, and process/thread activity. By applying filters and capturing live streams, you can diagnose software faults, track changes, and audit behavior on Windows.
Procmon64 uses a kernel-mode driver to intercept I/O and registry calls, logs events with timestamps, and renders them in a filterable UI. It can save traces as PML or export to CSV for offline analysis.
Quick Fact: Process Monitor was created by Mark Russinovich and kept by Sysinternals; it provides low-level system activity details not always visible in Task Manager.
What procmon64 Captures
- Live Trace: Real-time capture of file, registry, and process activities
- Filter Engine: Advanced filters to isolate events by path, operation, or PID
- Trace Viewer: UI that lists events with columns for time, operation, path, result
- Log Export: Export traces to PML or CSV formats
Is procmon64 Safe?
Yes, procmon64 is safe when downloaded from the official Microsoft Sysinternals site and executed as intended.
Is procmon64 a Virus or Malware?
The real procmon64.exe is not a virus. Malware may imitate Sysinternals tools, so verify digital signatures and trusted source.
How to Tell if procmon64 is Legitimate or Malware
- File Location:: Must be in
C:\Sysinternals\Process Monitor\Procmon64.exe or copied from an official Sysinternals distribution.
- Digital Signature:: Right-click Procmon64.exe → Properties → Digital Signatures. Should show signing authority "Microsoft Corporation".
- Resource Usage:: Typical idle usage is low; high sustained CPU during capture indicates active monitoring but unusual spikes when idle warrants review.
- Behavior:: Procmon64 should start only when launched by the user; background auto-start is not expected.
Red Flags: If procmon64.exe is found in unexpected folders (like Temp or AppData), runs without user action, or lacks a valid signature, scan with a reputable antivirus.
Why Is procmon64 Running on My PC?
procmon64 runs when you start Process Monitor to trace real-time activity across the file system, registry, and processes for debugging and security investigations.
Reasons it's running:
- Active troubleshooting: You're collecting live data to diagnose a Windows or application issue.
- Real-time monitoring: Process Monitor captures events as they occur to help correlate actions.
- Filter-driven focus: Saved filters limit output to relevant paths and operations.
- Post-incident analysis: Trace data supports security investigations and forensics.
- System auditing: Used by IT teams to audit software behavior and permission changes.
Can I Disable or Remove procmon64?
Yes, you can stop and remove procmon64. It's a standalone tool; simply delete the Procmon64.exe and its accompanying files from the Sysinternals package.
How to Stop procmon64
- End Active Capture: In Process Monitor, click the 'X' to stop capture and exit.
- Close the Application: File > Exit Process Monitor or close the window.
- Shutdown System Monitor: Ensure no other Sysinternals tools are running in the session.
- Remove Files: Delete the Procmon64.exe and related files from the distribution directory.
- Optional Cleanup: If added to PATH or a shortcut, remove those references.
How to Uninstall Procmon64
- ✔ Delete the Procmon64.exe and accompanying files from the Sysinternals distribution folder
- ✔ Optionally remove the Sysinternals folder from your system
- ✔ No registry entries or installers are required; just delete the files
Common Problems: Real-time Monitoring with procmon64
If procmon64 is not capturing events or shows unexpected behavior, try these fixes.
Common Causes & Solutions
- No events captured: Verify that you started capturing (Capture Events button) and that you have proper access rights for the monitored objects.
- High CPU usage during capture: Limit event types, reduce filter scope, and ensure you're not capturing network events unnecessarily.
- Too large trace files: Use filters and Set Maximum File Size; prune older traces to manage storage.
- Permission denied: Run Procmon64 as Administrator or adjust UAC permissions for the user.
- Corrupted trace file: Save a fresh trace and verify the integrity of the PML file; re-run capture if needed.
- Driver not loaded: Procmon64 relies on a driver; ensure the Sysinternals driver is properly installed and loaded.
Quick Fixes:
1. Open Procmon64 and start capturing; ensure you have a filter to avoid excessive data
2. Run Procmon64 as Administrator to access all monitored objects
3. Set up appropriate filters to limit event types and paths
4. Clear any previous logs or save traces for offline analysis
5. Check for updates from the Sysinternals site and replace the tool if needed
6. If performance is an issue, disable network events or disable capturing temporarily
