Where Is It Located? (The Best Safety Check)

Legitimate commwatch.exe should live in a specific folder. Here’s how to check:

Open Task Manager (Ctrl + Shift + Esc).
Find commwatch.exe in the list.
Right-click it and select “Open file location.”

Safe path (typical):

C:\Program Files (x86)\Sierra Wireless Inc\Common\commwatch.exe

C:\Program Files\Sierra Wireless Inc\Common\

Red flags (possible malware):

Running from C:\Windows\Temp\
Running from C:\Users\[YourName]\AppData\Local\Temp\
Running from C:\ProgramData\ (with an obfuscated folder name)
The file is not digitally signed by “Sierra Wireless, Inc.”

2. High CPU or Memory Usage

Cause: A memory leak in an older version of SoftEther VPN (pre-2018). Also, if you have a "packet logging" feature enabled, commwatch.exe will write logs continuously, consuming CPU cycles.

commwatch.exe

Type: Executable program (Windows)

Summary:
commwatch.exe is a Windows executable commonly associated with tools that monitor, log, or manage communications — typically serial/COM ports, modem activity, or network communication channels. It may be used by developers, IT administrators, or diagnostic utilities to capture and display data flowing through communication interfaces in real time.

Red Flags (Indicates Malware)

If you observe any of the following, run a full antivirus scan immediately:

commwatch.exe runs at startup even though you never installed a VPN or connection sharing tool.
You cannot find the file in Program Files but it appears in %temp% or C:\Windows.
Task Manager shows the process as "32-bit" but you have a 64-bit system and it’s running from a system folder.
Your antivirus (Windows Defender, Malwarebytes, etc.) flags it as a Trojan like Trojan:Win32/Wacatac or PUA:Win32/SoftEther.

Note: Some lesser-known antivirus engines may flag the genuine commwatch.exe as a "Potentially Unwanted Program" (PUP) because it can be used to bypass network restrictions. This is often a false positive.

High CPU / Memory Usage

Possible cause: Corrupted token database or excessive log file size.
Fix: Restart the CRYPTO-Server service, clear old logs (via CRYPTOCard admin console), or update to the latest version.

How to Fix commwatch.exe Errors (Keep It, But Repair It)

If you want to keep using SoftEther VPN and commwatch.exe but you are experiencing crashes or high resource usage, try these fixes:

Update SoftEther VPN: Download the latest version (currently 4.x or 5.x) from the official website. The developers fix memory leaks regularly.
Reinstall the network adapter: Open Device Manager, go to Network adapters, find the "SoftEther Virtual Ethernet Adapter," right-click and uninstall it. Then reinstall SoftEther VPN.
Disable Packet Logging: In the SoftEther VPN Server Manager, navigate to your Virtual Hub > Log Settings. Disable "Save Packet Log" and "Save Security Log." This dramatically reduces CPU usage.
Exclude from Antivirus: Add commwatch.exe to your antivirus's exclusion list to prevent real-time scanning from interfering with its network operations.

How to Remove or Uninstall commwatch.exe

Depending on whether the file is legitimate or malicious, the removal process differs.

The Bottom Line

commwatch.exe is a legitimate but specialized process from Conexant for managing dial-up modems and fax hardware. On modern systems without a modem, its presence is unusual and warrants investigation. Always verify the file's digital signature and location before assuming it is safe.

If you run a modern PC (post-2015) that has never had dial-up internet, you can safely uninstall any associated Conexant software. If you find the file in AppData or Temp, treat it as a high-probability threat and scan immediately. When in doubt, upload the file to VirusTotal and let 60+ antivirus engines decide for you.
