No. If you like the outbound firewall you can use it. Just in average,
for the average user, in my experience people tend rather to believe
they are safe because they have a outbound firewall and it does not
report anything instead of being careful. If you are very careful, you
can add your outbound firewall if you think you need it. Just the blind
advice "use this and you are safe" is just wrong. And the basic design
to mix an outbound firewall with some inbound firewall and some
intrusion detection system and some privacy control function and some
parental control system and some more is just wrong. In most cases, if
you knock out one of those things you knock out the whole thing. If it
crashes it usually crashes completely. If you think, you need an
outbound filter, get an outbound filter and run it separately from the
inbound filter. Same results and you most likely think a little bit more
about what you get for your money. With a PFW it's all there and nobody
really thinks about what each part does and how reliable it actually
works. (And no PFW maker will tell you...)

> recommend AVs/adware progs etc that the "security conscious" should have

None. I don't need any. No malware gets onto my computer. So why should
I scan for some? My AV is the most useless thing on my computer and I
only have it because I want to know how good it works as I have it
running on some other people's computer as well. The last time it popped
up was with some uesless warning regarding a phising e-mail before I
even could read it. Jeez, how should someone learn to distinguish
between a real and a fake email if they don't even see it. Someone
recently wrote that he was so glad to have his AV because it prevented
an infection of his computer with a Trojan./Phish.blablabla. It was just
a simple phising e-mail. A phising e-mail is harmless until you click on
the link which guides you somewhere else. Before that, it is harmless.
(I played a little bit around with it and found the most disturbing
message the warning that there is a phising e-mail in my Trashbin once
I moved it there. So you get a warning message for some really good
practice like trashing a phising e-mail instead of clicking on it...)

No double standard. You don't need one if you are careful.

Yes. None is the worst possible. ;-)

Good, then your firewall did have some purpose for you. Please allow me
to ask how it happened and what your expectations have been of your
firewall and AV before that and after that? Did they change?

I know all my processes on my computer.

I install/recommend people AVs and PFWs only together with a long list
of warnings that AV and PFW is just and only and nothing more than a
backup net with huge holes in it. If you fall, it may or may not catch
you. And you may never notice that you fell. (O.K. weird picture ;-) I
tell them, that if there is a warning message popping up, they have
already lost. If they tell me, they got one, and it's a real one (not
the phising thing above still far far away from the real danger of
clicking on it) I start using all those other adaware tools a.s.o on
their computer to make sure that it was really the first and only time.
   Occasionally (depending on how stubborn the user is) I just take the
image of the first installation and restore it, telling them that to
verify their computer is clean after they actually tried to open this
PIF attachment takes a couple of hours and never is 100% sure. So you've
lost your life. Game over. Start again... ;-) If I found some malware
despite the AV and PFW I always find some more drastic measures to lock
down the computer further which is however a little bit more intrusive
when they for instance cannot install any software anymore without
consulting me first. I remove IE and OE/Outlook from their computers and
replace them with Firefox and Thunderbird. That comes with a list of
warnings, too, never to install an extension if the question pops up.

I am looking for a good, valuable replacement of the PFW part, though,
that gives me satisfactory outbound filtering and good warnings and
which is fully newbie usuable, because I don't really see any good use
for any of the other PFW features beyond the outgoing application filter
and a PFW is a hell complicated to configure to let it run without
bigger problems (i.e. endless question dialogs) on a newbie computer.
