"Cut off one head, two more shall take its place!"

Hydra is a Windows virus that displays a message box. When you close a message box, 2 more will show up.

This virus was implemented using Visual Basic and .NET 4.7.1.

To shut it down complete, you can use Task Manager. If the Task Manager is disable, do the following steps to enable it:

  • Open Registry Editor
  • Locate Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System
  • Open DisableTaskMgr, enter 0 to Value data
  • Click OK

To stop the virus from running at Windows startup, do the following steps:

  • Open Registry Editor
  • Locate Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
  • Delete the Hydra registry value

Note that this virus is harmless ๐Ÿ™‚ If you know how to make it more annoying (for example: Task Manager can't shut it down), feel free to contact me

(so that means Task Manager is Captain America ๐Ÿค”)

HAIL HYDRA!
