WPKG Package

This is a silent installer and uninstaller for Microsoft Security Essentials, Windows XP, US English, 32-bit version.

<package
	id="microsoft-security-essentials"
	name="Microsoft Security Essentials"
	revision="2"
	reboot="false"
	priority="1">

	<check
		type="uninstall"
		condition="exists"
		path="Microsoft Security Essentials"/>

	<install
		cmd='%SOFTWARE%\ms_security_essentials\mssefullinstall-x86fre-en-us-xp.exe /s /runwgacheck' />

	<upgrade
		cmd='%SOFTWARE%\microsoft-security-essentials\mssefullinstall-x86fre-en-us-xp.exe /s /runwgacheck /o' />

	<remove
		cmd='%SOFTWARE%\ms_security_essentials\mssefullinstall-x86fre-en-us-xp.exe /s /u'/>
</package>

Note than an upgrade line is required because although the program may update itself (though I'm not certain it does), if you bump the revision number then WPKG will want to run an 'update'.

Installer command-line switches

  • /s - perform a silent installation
  • /runwgacheck - automatically perform a Windows Genuine Advantage check
  • /o - don't automatically run the updater and the system scan after installation - when you then login it may then give a red indicator and say that real time protection is off because virus definition files are out of date. I've had a few differing experiences at this point, either it updates them quickly automatically, or if you click on the system tray icon it tells you it's out of date but then updates it quickly, or it displays this then just waits for you to manually press the 'Update' button.. This is as both an Administrator and as a Restricted User.

Gotchas

  • Soon after installation it can recognise potentially useful software as a threat. For example if you have UltraVNC installed it will flag up UltraVNC.exe and RealVNC.exe. There's a risk that a user, when prompted to quarantine such files, will choose to do so and remove the administrator's ability to connect.

It would be useful to script the white-listing of specific files that should not be considered a threat. White-listing can be performed maually using: Show details → Recommendation → Select an action → Allow → Apply actions (note that Close means 'don't take any action at this point') → Close - this is saved system-wide.

Updates

Virus Definition Updates

Virus definition updates are automatically downloaded and used.

Program Updates

Does anyone know how it handles program updates? F-Prot, for example, runs as a service so is able to automatically update itself whether or not a user is logged in as an administrator, power user or restricted user.
