This isn't a Linux problem. Best idea would be running Linux on
all systems, to save you work setup a LTSP ( )

If you insist on running doze you need to firstly clean out
virus/malware from the systems. This includes IE + Outlook, most
virus/malware targets them, some say they are virus/malware on
their own.

Now install firefox/mozilla and use this for surfing + mail, you
have reduced the risk of new problems in a second about 80-90%.

There are a few things squid can do for you, like Squidguard and
Dansguard (see below URL), this needs lots of work and can't
guarantee anything but you'll have much more success with
removing IE + Outlook firstly.

It doesn't sound as if it would be possible to educate your users
at all? More like they'd happily click on anything and wonder
later they did brought down their own system and perhaps the rest
of your network to a grinding halt.

Many crap comes as mail, running virus protection + SA
(SpamAssassin) on your MTA and dropping/rejecting the crap should
help in addition.

Not a good idea to disable icmp messages.

Doesn't really matter, as outlined to yourself a big favor and
remove the No. 1 reason for catching all the crap.

Good luck
