We are an Virus Scan Enterprise shop and Adobe flash player is installing "McAfee Security Scan" which is interferring with our users' productivity by causing error messages to pop-up. We want to uninstall this across the enterprise by using a batch file but cannot determine the "silent" options to use on the uninstaller. 'C:\Program Files\McAfee Security Scan\uninstall.exe' brings up a box in which the user must click 'Uninstall' and we would like to force that uninstallation and make it invisible to our end-users. What command-line options are available to force the uninstallation, quietly if at all possible, of McAfee Security Scan? (original question asked by jcstevens - not related to my company at all but answer still needed and suspect that others need also).
McAfee Security Scan is additional option when installing Adobe flash. Ultimately when installing Adobe flash you would want to deselect the option to install the McAfee Security Scan. This particular product is designed for consumer use, so we do not have silent installation information for this product available in corporate support. The information that I have found on this references the uninstall via the program group. I have been advised that you can contact consumer McAfee support to see if they might have some additional information on silent uninstall options.
McAfee Security Scan uses the Nullsoft Installer NSIS 2.22 as installer. Therefore you can apply /S to the UninstallString defined in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\McAfee Security Scan
Therefore "C:\Program Files\McAfee Security Scan\uninstall.exe" /S should do the trick.
Note that /S is case sensitive.
By the way: http://unattended.sourceforge.net/installers.php provides a good list of installer products widely used and describes some of their parameters.
