STEP 1: Use Rkill to terminate malicious processes

In this first step, we will download and run Rkill to terminate malicious processes that may be running on your computer.

RKill is a program that was developed at BleepingComputer.com that attempts to terminate known malware processes so that your normal security software can then run and clean your computer of infections. When RKill runs it will kill malware processes and then removes incorrect executable associations and fixes policies that stop us from using certain tools.

1. Download Rkill.

   You can download RKill to your computer from the below link. When at the download page, click on the Download Now button labeled iExplore.exe. We are downloading a renamed version of Rkill (iExplore.exe) because some malware will not allow processes to run unless they have a certain filename.

   (The above link will open a new page from where you can download Rkill)

2. Run RKill.

   After downloading, double-click the iExplore.exe icon to kill malicious processes. In most cases, downloaded files are saved to the Downloads folder.
   The program may take some time to search for and end various malware programs.

   

   When it is finished, the black window will close automatically and a log file will open. Do not restart your computer. Proceed to the next step in this guide.

STEP 2: Uninstall malicious programs from your computer

In this second step, we will manually check if any unknown or malicious programs are installed on the computer. Sometimes adware and browser hijackers can have a usable Uninstall entry that can be used to remove them.

Now that the malicious programs have been removed from your computer, we can proceed with the next step in this guide.

STEP 3: Remove malicious browser policies from Windows

In this third step, we will download the Chrome Policy Remover file (credits to Stefan Van Damme) and remove the malicious browser policies. .

1. 
   

   Download the Chrome Policy Remover.

   
   

   Download the “Chrome Policy Remover for Windows” file from the below link. This file is a batch script designed to automatically remove Chrome policies.

   

   CHROME POLICY REMOVER DOWNLOAD LINK
   (The above link will download delete_chrome_policies on your computer.)
   
   

   Note: Windows might display a security warning because the file is a batch script (.bat). This is a standard security measure. Since the Chrome Policy Remover is a trusted tool, clicking “Keep” allows you to proceed with the download.

2. Right-click “delete_chrome_policies.bat” file and select Run as administrator

   We will now run the “delete_chrome_policies.bat” fiel as administrator.Running the delete_chrome_policies file as administrator grants it the necessary permissions to modify system settings related to Chrome policies. This ensures the tool can effectively remove the policies.

   

3. Click Yes/Run at the confirmation prompt and allow the process to complete.

   Windows will ask for confirmation before allowing the script to make changes. Clicking “Yes” or “Run” (depending on your Windows version confirms your intent to run the tool and remove the Chrome policies. The script will then run and automatically remove the policies, after which you can close the command prompt window.

   
   

   

Now that the malicious policies were removed, in the next step, we will reset your browser settings to their defaults.

STEP 4: Remove malicious files and folders from Windows

In this fourth step, we will manually search and remove malicious scheduled tasks and folders on your computer.

1. Delete malicious scheduled tasks.

This infection may create a malicious scheduled task in the Task Scheduler to ensure that it is automatically reinstalled every 5 minutes after it has been deleted. This task may run at regular intervals to ensure that the infection persists on your system.

1. Search for “Task Scheduler” in the windows search as shown below..
   You can also open the Task Scheduler app by pressing the Windows + R buttons and then type “taskschd.msc” and press Enter.
2. In the Task Scheduler window, navigate to the Task Scheduler Library on the left side of the screen.
3. Locate the malicious scheduled task in the list of tasks. It may have a randomly generated name (eg. Chrome_Policy, Chrome_Bookmarks, Chrome_Folder) or may be identified as a suspicious or unknown task. Right-click on the malicious task and select “Delete” from the menu.

2. Delete malicious files located in AppData\Roaming folder

We will now delete the malicious file that is located in the AppData\Roaming folder.

1. Search for “Run” in the windows search as shown below, or press the Windows + R button to open the Run app.
2. In the run app text box, enter “%AppData%” and click OK. Windows will directly open up the Roaming folder which is inside the AppData folder.
   

   

3. In the AppData\Roaming folder, search and delete any unknown folders with names like Default, Chrome32, Energy, Bloom, and Travel (note that the actual name on your computer may be different, but you should look for programs with similar naming conventions).

3. Delete malicious files located in AppData\Local folder

Next, we will delete the malicious folders that are located in the AppData\Local folder and the malicious Chrome browser extensions.

1. Search for “Run” in the windows search as shown below, or press the Windows + R button to open the Run app.
2. In the run app text box, enter “%localappdata%” and click OK. Windows will directly open up the AppData\Local folder which is inside the AppData folder.
   

   

3. In the AppData\Local directory, search and delete the Default, WindowsApp and ServiceApp folders.

   Next, find the Google folder and go to Google > Chrome > User Data > Default (or Profile) > Extensions. Find the malicious extension folder within the Extensions folder and delete it. It may have a randomly generated name or may be identified as a suspicious or unknown extension.

   

4. Remove Chrome Shortcut Modification

This malware can hijack your browser shortcuts to target the malicious files. Here is a short guide on how to remove the Chrome shortcut modification:

1. Right-click on the Google Chrome shortcut on your desktop or Start Menu and select “Properties“.
2. Under the Shortcut tab, look for the “Target” field. This is where any added commands to the shortcut will be. Carefully examine the target path and remove any suspicious looking text that may have been appended, especially anything referencing the AppData folder.
   For example, remove text like “–load-extension=C:\Users%USERNAME%\AppData\Local\Default”.
   The target should point only to the chrome.exe file location, nothing more.
3. Click OK to save the changes and close Properties.
4. Launch Chrome again normally through the shortcut. The extension should no longer load on start up.

You can also right click the shortcut and select “Open File Location” to open the chrome.exe folder. Drag chrome.exe directly to your taskbar to create a clean shortcut.

Now that we have manually removed the malicious tasks and folders from your computer and cleaned your browser shortcuts, we can continue with the next step.

STEP 5: Reset your browser settings to their defaults

In this step, we will remove spam notifications,  malicious extensions, and change to default any settings that might have been changed by malware.
Please note that this method will remove all extensions, toolbars, and other customizations but will leave your bookmarks and favorites intact. For each browser that you have installed on your computer, please click on the browsers tab below and follow the displayed steps to reset that browser.
