Brief Description 

    

Janpra.A is a worm that carries out several modifications in the Windows Registry, which prevent the user from working with the computer as usual.

These modifications prevent the user from carrying out the following actions, among others:

  • Running files in a fast and straight way, as it disables the option Run from the Start menu.
  • Viewing the processes that are being run through the Task Manager.

Additionally, it modifies the text that appears as the title of the Internet Explorer windows.

Janpra.A reaches the computer in a file with the icon of Windows Media Player and it spreads via removable, shared and mapped drives.

Visible Symptoms 

    

Janpra.A is difficult to recognize, as it does not display any messages or warnings that indicate it has reached the computer.
