Advanced Security Tool 2010 is a fake Antivirus tool.
It is from the same rogue family as Security Central, Home Personal Antivirus, XP Deluxe Protector, Win PC Antivirus, Win PC Defender, XP Police Antivirus, IE-Security, WinDefender 2009 and Total Secure 2009.
Once registered, SAdvanced Security Tool 2010 doesn't detect infections anymore (same system, no cleanings). There is no more fake alerts and disturbing warning messages... Easy proof of a scareware application.
If your PC is infected with Advanced Security Tool 2010, use MBAM to remove it
