Air Software

Warning, this is not the legitimate setup program for Adobe Flashplayer. The setup is bootstrapped by the Air Installer 'download manager' (a pay-per-install monetization download manager) that bundles unwanted software (adware, toolbars, extensions) during setup while deciving the user into thinking they are downloading the stadard installation setup from Adobe Flashplayer. The application update.exe by Air Software has been detected as adware by 30 anti-malware scanners. The program is a setup application that uses the AirInstaller Download Manager installer. This program installs potentially unwanted software on your PC at the same time as the software you are trying to install, without adequate consent.
