i just would like to know if uploaded themes are checked for viruses, trojans and/or spyware.

while i don't know of any theme which ever contained even one of these, i'd surely be easy to infect a lot of computers that way, with possibly disastrous results...

You should check themes yourself before using them, as you should with any software you download.

I don't know of any anti-virus tools for detecting windows virii on a alternative os box. And no...Im not stupid enough to put LSnet on an IIS box so we can do that. I may be crazy...but not stupid.

nobody said you were stupid - at least i didn't. :P
i just wanted to know... of course it's up to everybody him/herself to check.
