One of the REG_EXPAND_SZ values on the right is the UninstallString.  If you copy that value and paste it into the command line, it will politely ask:  Are you sure you want to uninstall this product?  If you are sure you want to uninstall it, go ahead and hit Ok.

If you want to get rid of both pieces of Forefront ( the Security State Assessment Service, and the Client Security Antimalware Service) you will need to find both registry keys and run both uninstalls.  There is a catch though…  the Client Security Antimalware Service has a value that looks like this: MsiExec.exe /I{436028CD-6476-4224-9274-8F0320F30FD1}.  To get it to uninstall, you need to change the /I to /X like this MsiExec.exe /X{436028CD-6476-4224-9274-8F0320F30FD1}.
