protection through one computer

[giddyup]

If one computer has two network cards installed, one to the internet and
a second computer is hooked through the first computer (with the two
cards) will the first computer with two cards antivirus etc. protect the
second?

NO!

Standard Windows protection only protects the PC that this protection
is installed on.

The only protection that might be in effect would the a firewall
protection.

It depends on user practices and the AV software and how you set it up. AVG
(from Grisoft) has some very agressive protection modes, and can also be set
to regularly scan the other computer as well as the one it's on.

Most critical is whether the users practice safe hex - not down-loading and
running everything they come across. To protect both machines against this
kind of behaviour, you need the AV on both machines, set to scan when a file
is written.

I would go with a paid version of AVG on the 'host' machine and a free
version (if this is for home use) on the other.

FWIW, I am not claiming that only AVG will do this, or that there aren't
equivalent and/or better AV programs out there.

Those answers provided little help since 'reasons why' were not
explained.

Using a second computer means malware that attacks open ports would
not attack open ports on the first computer. But that type of malware
is long gone; made irrelevant because ports have been closed and then
further made resilient by firewalls. Anything that a second computer
might do is no longer the major threat and should already be inside
the first computer.

Other more devious malware enters as attachments to e-mail, ActiveX
programs, in graphic files, or other executables. Obviously, a second
computer does not block e-mail or downloaded executables. Even a
firewall does not provide that protection. Thesefore also install
virus protection software - another protection layer located only on
the first computer.

Not as such. However you can configure it to act as a hardware-firewall to
protect against incoming and outgoing threats as well as scan traffic. You could
even set it up to act as an anti-virus scanner, email server, etc. the way that
enterprises do. Almost a decade ago, I knew a guy in class who had set up a
system as a firewall for his main system, so I can only imagine what the
possibilities are today.

Google for "hardware firewall" or "set up system as firewall"
