  I am trying to get information about the current status of the firewall and anti-virus application (status ok, deactivated, anti-virus definitions out of date and so on). The application we are writing won't be updated frequently, so checking registry keys of the different AV-vendors doesn't seem to be a good idea (AV Vendor releases a new version --> registry keys change --> our application doesn't deliver the right information anymore). ...Show All
