Windows Security Suite is a new fake security scanner (rogue). It belongs to the same family as Malware Destructor 2009, FastAntivirus,
MalwareCatcher, VirusShield, Extra Antivirus, Virus Sweeper, Ultra Antivir 2009, Virusdoctor, VirusMelt, VirusAlarm. Windows Security Suite comes from fake online scanners and detects nonexistent malwares to scare users pushing them to buy a license.
