want to know just what info you're broadcasting on the net & how vulnerable you are? Go to https://grc.com/x/ne.dll?bh0bkyd2 , and scroll down the page to "Test My Shields!" and "Probe My Ports!" and try the two out. You may be very surprised (and worried) at what you discover. And FWIW I'm not affiliated with those folks in any way. If you prefer, you can do a web search & find plenty of other sites out there that will test your security.
