How to Uninstall the Navidad Trojan Virus

The Navidad Trojan virus is a relatively new Internet threat. This virus infects computers via email. The subject of the email will read “RE:” and the email has an attachment called. Navidad.exe. On execution, a message box appears and maps the opening of Windows executables. This causes the file to be executed whenever an EXE file is opened, causing most Windows programs to not work properly. In order to delete the Navidad Trojan horse, you will need to edit the registry. Read on to learn how to do this manually or using a tool called "fix_navi.com" :

Instructions

Difficulty: Moderate

Manually Remove the Navidad Trojan Virus

1. Change the file extension of The Registry. You need to do this because the Navidad disables all executable files and the Registry Editor is an executable file.
2. Click on the START button located at the bottom-left corner of the desktop. Click "Search" in the Start menu. Search for the following file: "regedit.exe."
3. Change the file extension from ".exe" to ".com" To do this, right-click on the file and click "Rename." Rename this file from "regedit.exe" to "regedit.com."
4. Run the Registry Editor by clicking on the "Start" button and then clicking "Run." Type in regedti.com and then click "OK." The Registry Editor should open. Go to the left pane and click the plus signs to navigate to the following registry entry: HKEY_CLASSES_ROOT\exefile\shell\open\command.
5. Look in the right-hand pane and double-click the entry that's named: (Default) = "\WINNT\SYSTEM32 WINSVRC.EXE"%1"%*". This will open the "Edit" window. Delete the first part of the string, leaving only "%1"%*".
6. Navigate to the following registry entry: HKEY_LOCAL_MACHINE\ Software\Microsoft\Windows\CurrentVersion\Run. Click Delete Win32BaseServiceMOD = WINNT\SYSTEM32\WINSVRC.EXE. Navigate to the following registry entry: HKEY_CURRENT_USER\Software\Navidad. Delete this registry key.
7. Close the Registry Editor and restart your computer. After your computer reboots, use an up-to-date antivirus to scan your computer.
8. Make sure you rename the file from regedit.com back to regedit.exe.
