Hi utonto, I'm sure you'll get other (and better) replies...however in my case I use the limited setting for apps like browsers, e-readers, pdf, word processors, media players etc. (I have an Asus computer also but don't go overboard with trying to set system or other files/apps to "limited". Of course you can try it with anything you like and if it causes issues just change the setting.) The idea being that if any of these apps somehow got infected they would be limited in the mayhem that might ensue. (I also keep most of them sandboxed with Sandboxie which is a great complement to PrivateFirewall imho but that's another topic altogether and best not to flesh out too much here.) Hope that helps a bit.
