chrome_update.exe

Google Chrome

Air Software

Warning, this is not the legitimate setup program for Google Chrome. 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 Google Chrome. The application chrome_update.exe, “Google Chrome ” by Air Software has been detected as adware by 33 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. With this installer, users are expecting to download Google's Chrome web browser but before that occurs they may be presented with additional offers, mostly potentially unwanted software or adware.
