Can you get free satellite tv over the Internet like I've seen advertised.

if it’s over the internet, then it’s not satellite, right?

the truth is, unless you get video content directly from a network’s own website (eg, i watch “lost” on abc’s website) you’re probably getting an illegal copy.

i couldn’t say whether such content is virus-ridden; i have a mac and there are no viruses for macs. but i can say with confidence that the offer you’re reading about is either misleading or illegal. if something sounds too good to be true, it probably is.
