Uninstalling Trend Micro Security Agent Without Password: A Step-by-Step Guide for IT Professionals

Introduction

----------

Trend Micro is an effective antivirus software widely used by individuals and organizations alike due to its robust protection against various malware threats. However, sometimes situations may arise where you need to uninstall the Trend Micro Security Agent without having access to the password that was set during installation.

Fortunately, there are ways through which IT professionals can accomplish this task efficiently using either manual methods or automated scripts deployed via Remote Management and Monitoring (RMM) tools like Microsoft System Center Configuration Manager (SCCM).

In this article, we will focus on providing a detailed guide for uninstalling Trend Micro Security Agent without needing the password. We'll cover both traditional steps as well as offer insights into creating an automation script to streamline the process further.

Pre-Requisites

--------------

Before proceeding with these instructions:

1. Ensure you have administrative privileges on your Windows machine.

2. The computer should be running a supported version of Microsoft Windows (XP SP3 or later, Vista Service Pack 1 or higher).

3. Trend Micro Security Agent must already be installed and running.

Manual Uninstallation Steps

--------------------------

### Step 1: Open the Start Menu

Press Win + R keys on your keyboard to open Run dialog box.

### Step 2: Type supporttool.exe & Press Enter

In the text field, type `supportTool.exe` (with a capital 'T') and press ENTER. This will launch the Trend Micro Support Tool.

### Step 3: Click Yes in User Account Control Window

When prompted with 'Do you want to allow this program to make changes to your computer?', click Yes to grant necessary permissions.

### Step 4: Open Trend Micro Diagnostic Toolkit & Navigate to Uninstall Tab

The Trend Micro Support Tool will now open. On the left-hand side navigation panel, double-click on (C) - Advanced Options, then select the tab labeled as Uninstall at the top-center part of the window.

### Step 5: Stop All Components & Wait

In this screen, locate and click on Stop all components. Allow a few seconds (approximately 10-15) for all processes to completely terminate before proceeding further.

Wait until you see either:

a) The Trend Micro icon in the taskbar notification area has disappeared.

b) A 'Components stopped successfully' message appears at the bottom right corner of your desktop screen.

### Step 6: Verify Uninstallation & Restart Computer

Once both conditions are met, close all instances of Task Manager and Device Manager. Reboot your computer to ensure that Trend Micro Security Agent has been completely uninstalled from your system.

Scripting the Uninstall Process

------------------------------

For organizations or IT professionals looking for a more efficient solution to mass-uninstall Trend Micro Security Agent across multiple machines without requiring manual intervention at each device, you can create an automation script using tools like PowerShell or vbscript. Below is an example batch file that accomplishes this task:

```batch

@echo off

:: Set path to supporttool.exe based on your installation location

SET SUPPORTTOOL=C:\Path\To\SupportTool.exe

:: Run the Support Tool and wait for 30 seconds before proceeding further

START '' '%SUPPORTTOUL%' /npuw30000 & ping -n 10 >nul2null

:: Wait until all components are stopped (max waiting time: 5 minutes)

:wait_for_stopage

tasklist | find 'tmcfmrpr' > nul2null

if %errorlevel%==0 (

echo Trend Micro Security Agent has been successfully uninstalled.

exit /b 0

) else (

timeout -m3 & goto :wait_for_stopage

)

echo Error uninstalling Trend Micro Security Agent. Please manually intervene and refer to the article for further assistance.

exit /b 1

```

In this script:

* Replace `C:\Path\To\SupportTool.exe` with the actual path where you've extracted or installed the Support Tool executable.

### Deployment via RMM

Once your batch file is ready, save it somewhere accessible by all machines in a shared network location. Then use tools like SCCM to deploy this script as an elevated application through group policy objects (GPOs) or simply double-clicking on it from within an already running session of PowerShell/ISE.

-------

In conclusion, following these steps will help you uninstall Trend Micro Security Agent without needing the password that was set during installation. Remember always back up important data before attempting any system changes and test your scripts in a non-production environment first to ensure they work as expected.
