.SYNOPSIS
Gets Windows Firewall Profile status and checks for installed third party security products.
.DESCRIPTION
This function operates by examining registry keys specific to the Windows Firewall and by using the
Windows Security Center to get information regarding installed security products.
.NOTE
The documentation in the msdn is not very clear regarding the productState property provided by
the SecurityCenter2 namespace. For this reason, this function only uses available informations that were obtained by testing
different security products againt the Windows API.
