Step 1: Restart in Safe Mode with Networking

Booting into Safe Mode disables unnecessary startup programs, including most malware.

1. Press Windows + R, type msconfig, and hit Enter.
2. In the System Configuration window, go to the Boot tab.
3. Check Safe boot, then select Network.
4. Click Apply and restart your computer.

Step 2: Terminate Malicious Processes

1. Open Task Manager using Ctrl + Shift + Esc.
2. Navigate to the Processes or Details tab.
3. Identify any unusual or unrecognized processes. Be cautious—do not stop critical Windows processes.
4. Right-click a suspicious process, choose Open File Location, then End Task.
5. Delete the associated file from the opened folder.

Step 3: Delete Trojan Files

1. Press Windows + R, type %appdata%, and press Enter.

   • C:\Program Files
   • C:\Program Files (x86)
   • C:\Windows\Temp
4. Delete any folders or executables related to the Trojan.

Step 4: Clean Up the Windows Registry

1. Press Windows + R, type regedit, and press Enter.
2. Go to these registry paths:
   • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
   • HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
3. Look for registry entries with unusual names or links to suspicious files.
4. Right-click and delete the unwanted entries.
