WinPC Antivirus is a Fake Security application. It replaces WinPC Defender.
These rogues are from the same creators of XP Police Antivirus, IE-Security, WinDefender 2009 and Total Secure 2009.
Once registered, all the fake malwares detected are now missing. And it looks like designers forgot to remove a part of the GUI Skin.
