Hi Ed,
For my money it would have to be hp-ux 10.x now 11.x.
It is a proven OS, can be hardended, and there is tons of support, i.e. this forum.
Unix in general is NOT virus prone, primarily due to a READ-ONLY kernel lock (windows kernel is dynamicly active while open, allowing writes), plus the fact there is no registry to work with nor application extensions to key on.
Linux is a great option to UX, only caveate at present might be driver accessability.
Nutshell;
If it were my business it would have to be HP-UX, primarily for the proven uptime capabilities and proven supportability

My 2 cents worth
