Artur Kozak

The installer which is distributed via file sharing sites such as TusFiles uses the 'download manager' which wraps the original file in a adware filled bundle. The application minecraftdl.exe, “Installer for QuickSet” by Artur Kozak has been detected as adware by 23 anti-malware scanners. The program is a setup application that uses the WebPick InstalleRex (Tarma) installer.
