Well Dan, wishfull thinking isn't going to change the facts of life, and
even thou there is a full Moon in Virgo perfecting DOS and 9x is way down on
the list of needs from things like a longer lasting light buld (coz we all
known there the GE bulbs are designed to burn out easily so you need to by
more. Up on a Gov building on Vancover Is. they have bulds still burning
that are 130 years old. I bought some of those 10 years bulds from the
handicap people. I was impressed that they did last over a year.)
Aside from rewriting history in one's own likeness, lol, how about just
hammering on about the basics.
Secure strong passowords, run under a user account for regular work. Two way
Firewall with as many ports close as possible, to the point of a little
inconvience. AV software, two kinds, one for the input streem, one for files
system and e-mail. Aware and spyware blockers and scanners - run often.
And last but not least, no fat, no dos, no multiboot.
The beat goes on, :)
