i think the question needing asking is "has anyone ever HAD a security breach"
i have never heard of one.
Bit like a home PC with so many companies inducing paranoia to sell their security products, "get the LASTEST and NEWEST proctection or you will LOSE ALL YOUR MONEY!!!!",when a windows firewall will do the job fine.
hell....i use to INSTALL virus's on my PC just to see is i could get rid of them and see what damage they could do....over 20 years of working and helping others, i have only had 1 serious virus where we just had to throw the drive out.
(had a character out of mad max jumping up and down, laughing in a satantic voice at bootup...pretty funny really. She was a complete noob and had no idea of what she did to get it there)
