Windows Defender (formerly Microsoft AntiSpyware) reports a file used by the Pharos Popup Client as the Rivarts.A trojan.

 

The registry key:

 

HKLM\System\CurrentControlSet\Services\mchInjDrv

 

Has been detected as malware by Defender.

 

Microsoft is aware of this problem. Other third party applications use the same hook. So far, however, Microsoft has not whitelisted the application, madCodeHook by Madshi.

 

Madshi, the developers of madCodeHook (the file in question) is also aware of this issue.

 

For more information on Madshi, and madCodeHook see: http://www.madshi.net

 

This is a required file needed for the Pharos Popup Client to function and does not pose a threat to the system.
