Hoisted by various petards of incompetence
Tell me again why supposedly "secret" systems:
1) Run cellar-tier dodgy operating systems by an American Company as well as dodgy applications by that same American Company, which is a known provider of Dodgy-ware on a regular basis.
2) Are apparently connected to the wide Internet doing I/O that no-one cares about.
3) Need to have something called "Antivirus" in the first place (what is it supposed to do? Patrol the gates of Castle Vania??)
Oh well, back to Symantec and the Yellow Sign I guess.
