Technical Details

This is the family description for the TotalDefender family of rogue antimalware programs.

Like most rogueware families, programs from the TotalDefender family will scan the computer system and then display fake alert messages stating that the system has been compromised. To deal with the supposed infections, the user is required to purchase a license to 'fully utilize' the program and/or 'enable' its disinfection functionality.


A typical installation from this rogueware family installs component files in:

  • %Program Files%\ [Name] Defender\

And adds the following registry key:

  • &HKEY_LOCAL_MACHINE\Software\[Name] Defender\

Where [Name] will typically be:

  • Windows
  • Total
  • IE
  • Malware

For example, the registry key may appear as HKEY_LOCAL_MACHINE\Software\Windows Defender\.
