Massive automation of the database creation would help. But I still can't
see any answer other than, "User is not able to install *any* software".

Like grannyx

Unfortunately, that's not an answer either - because if they can't install
software, they can't install patches and updates.

If you are relying on your users to install patches and updates, then
you have more to worry about then viruses..

Two words: Thinstall and remote home directories......

... ok maybe 5 words...

-JP
"Man that guy is Dumb"
-Algernon (sans flowers)

 And even a stripped-down
grannyx *will* have bugs that need patching.  Unless you're planning to
re-spin and re-ship CD's every 3-6 months, this is a non-starter.

I think the crucial point is "User is not able to *inadvertently* install
any software".  Given something like the Ubuntu updater with GPG signatures,
and a properly implemented SAK (Secure Attention Key) system so a browser
exploit can't fake the updater screen, it should (with suitable amounts of
handwaving) be possible to allow people to install software they *wanted*
to install, but prohibit drive-by fruitings of systems.

Yes, a *few* people will go out of their way and manage to install malware
anyhow.  But there's only one solution for them, and unfortunately it's
not politically expedient to suggest eugenics... ;)
