Atv flash virus or spyware question

Hi, I am interested in buying your product however can you please tell me whether you cater for any virus prevention on my home network? I have my apple tv connected via ethernet. Is it safe from viruses and spyware?

Any answers to this?

aTV Flash does not include an virus prevention software, though the built-in web browser does not support file downloads (by design).  This makes the likelihood of getting or passing along a virus on the AppleTV very, very slim.

I am not concerned that the apple tv will get a virus. I am more concerned that a virus gets spread onto my home network from my apple tv.
