Simple. Don't use public wifi if you are so paranoid about
security.

Please note there is no such thing as complete security and even
Micro**** will tell you that. Why do you think Micro****'s
products are still being pirated left, right and centre despite
all the anti-piracy measures implemented by nutters at Redmond
Hill? they couldn't even manage nntp groups so what made you say
they can secure your system fully? They keep pumping out security
patches month after month and the system is still the same!
