Moshe Karaso

This is a WebPick installer that bundles (with very minimal user consent) a number of adware browser extensions using the JustPlug.it browser framework. The application saveas.exe by Moshe Karaso has been detected as adware by 27 anti-malware scanners. The program is a setup application that uses the WebPick InstalleRex (Tarma) installer. The setup program uses Web-Pick's InstalleRex download manager and installer to bundle potentially unwanted ad-supported software which includes toolbars and browser extensions through a pay-per-install monetization scheme.
