Re: How isolated is the Host?

Windows XP support ends April 8th, 2014 and with no further security updates this is not the OS to be surfing the Internet with after that date!   That said, it doesn't matter what OS the Host or Guest is if there is connectivity between them or other systems they might connect to.  All appropriate security measures need to be taken on each system, physical or virtual, to guard against any threat as the only 100% assured way of not getting hit would be to turn the system off and never again turn it on!    Security is analogous to a block of swiss cheese in that there will always be some holes and the best defense aside from having appropriate software installed is not surfing indiscriminately.  How many teenage kids really care what sites they go to?
