Several trojans and backdoors have used names similar to commwatch.exe to avoid detection. These include:
If you do not actively use SoftEther VPN or a connection-sharing tool, simply uninstall it:
After uninstallation, commwatch.exe should be gone from Task Manager.
Message: "The instruction at 0x... referenced memory at 0x... The memory could not be read." Cause: A corrupted installation of SoftEther VPN or a conflict with another network driver (e.g., VMware, VirtualBox).
Since commwatch.exe is tied to modem drivers, you should uninstall the entire driver package rather than deleting the file manually (which could cause system errors or repeated error messages).
Method 1: Via Settings (Windows 10/11)
Method 2: Via Device Manager
Method 3: Manual deletion (advanced)

CommWatch.exe is a third-party RS-232 serial control software package typically used to manage professional audio-visual (AV) equipment, such as HDMI matrix switchers and scalers, from a PC. Technical Overview
Primary Function: Acts as a serial communication terminal that sends RS-232 commands to hardware devices. Developer: Often attributed to TEC-3 or VectorSoft.
Common Use Case: Configuration and switching of inputs/outputs on devices from brands like Monoprice, BZBGEAR, and Alfatron. Operational Requirements
To use CommWatch.exe for controlling a device, the software must be configured with specific communication parameters:
Baud Rate: Commonly set to 115200 (though this varies by device). Data Bits: Typically 8. Stop Bits: Typically 1. Parity: Typically None.
Command Syntax: Most professional AV devices require commands to end with a Carriage Return and Line Feed (
While CommWatch.exe is a legitimate utility for AV professionals, it is often flagged by users because it does not have a widely recognized digital signature.
Malware Concerns: If you find this file on a standard home computer without AV hardware connected, it may be a renamed malicious file. Legitimate versions are usually found in folders related to AV control software or copied manually to a PC for hardware setup.
High Resource Usage: If the process is using excessive CPU or memory, it is likely corrupted or infected, as a standard serial terminal should have a minimal system footprint. Common Deployment Steps Several trojans and backdoors have used names similar
Connection: Connect the PC to the hardware (e.g., a matrix switcher) via an RS-232 cable.
Installation: Copy the standalone executable to the PC (it often does not require a traditional "installer").
Execution: Launch the program and select the correct COM Port assigned to your RS-232 adapter.
Monitoring: Use the "Monitoring Area" in the software to confirm if sent commands were received and acknowledged by the device. User Manual - Alfatron Electronics

In most cases, a file named commwatch.exe is a legitimate diagnostic tool. However, because it is an executable (.exe), it can be targeted by malware authors who use similar names to "camouflage" malicious processes. Indicators of a Legitimate File:
Location: Legitimate versions are usually found in a subfolder of C:\Program Files related to VectorSoft or specific networking hardware.
Software Version: The most common legitimate version is 1.0. Red Flags (Potential Malware):
If you notice the following, the file may be a security threat: It is located in C:\Windows or C:\Windows\System32.
It has no visible window or user interface but consumes high CPU or network resources. Your antivirus flags it as a "Trojan" or "Agent". How to Verify and Manage the Process
If you find commwatch.exe running on your system and are unsure of its origin, follow these steps to verify its safety:
Check File Location: Right-click the process in Task Manager and select Open File Location. If it is in a temporary folder or a system folder without a clear program association, it is suspicious.
Inspect Properties: Right-click the file, go to Properties, and check the Details tab for a digital signature or copyright information from a known developer like VectorSoft.
Scan for Threats: Use the Microsoft Safety Scanner or a reputable tool like Malwarebytes to perform a full system scan.
Remove Orphans: If you see "Commwatch" in your Startup tab but have uninstalled the software, it may be an orphaned registry entry that can be safely disabled. I accidentally downloaded a .exe virus file - Microsoft Q&A
