When I setup wireless network at home, if one machine is infected with
virus, will the other machines be infected as well? Or if one machine
is hacked, will the others be infected too?

please advise. thanks!!

If your machines trust each other and one is infected, and the virus has
a infection vector across one of the trusts, then yes, your other
machines are likely to be infected.

It would depend on the hacker, virus, worm, and without further
information we couldn't go into specifics.

It would depend on which OS the other machines are running? If the
answer is Windows I would say YES.

Maybe. You have three separate computers. They may well all get infected by
the same outside source, they may infect each other, or they may get
missed.

Viruses are not some mysterious thing in the air, even if you use wireless.
They are specific pieces of data and programs that must be transfered and
run.

If their security isn't any better than that of the infected or hacked
machine, almost certainly.

If you have the SP2 firewall enabled, AND you aren't doing file or printer
sharing (which opens some of the the most vulnerable ports) then the risks
are small.

If any of the computers are sharing files or printers across the network
then you need to be more careful about your security settings, and having the
relevant security-patches applied for the known exploits which relate to
this.

With wireless it's important to use one kind of encryption or the other to
stop outside access. WPA is generally thought to be the better.

Not if you're using linux. There are no self-propogating linux viruses in
the wild.

If you're using NIS to authenticate users, a password compromise on one
machine will compromise all the others using NIS as well. Use strong
passwords, and change them regularly to reduce the likelihood of this
happening.

Well, if you're running Linux, viruses are not an issue. With Windows, they
can spread just as well as on a wired network i.e. virtually guaranteed to
spread.

If that attitude becomes widespread as more and more non-technical folks
start using Linux, you can be sure Linux will become a target.

Remember, the first reported Internet worm selectively infected Vaxen and
Sun boxes running Berkeley BSD UNIX.

Amen you hit the head on the nail. When the clueless reach Linux, the sharks
will follow. I use Linux too and I have seen some of the attack reports on
that O/S and heaven help Linux. Anything written by fallible Human Beings is
not infallible and if one thinks it is one is kidding one's self.
