You are far too paranoid. No home computer will get hacked. the 'alerts' are merely web handshakes from ISPs and servers that check to see if you are still online. Use you MacAfee AV and firewall and you will be more than protected. Home computers contain utter drivel that, whilst important to th owner is dull, dull, dull to the outsider. the Gibson Leak test is a little over the top as is the man himself. he used to be a marketeer and it shows.
