Internet Paranoia

[mark76g]

Hi,
Can somebody ease my paranoia on about the following issues ?

1) There has been alot of talk going around about poker bots. How common are they ?. If Somebody could design a bot that just played well enough to beat a few dollars an hour out of the low stakes tables they could just run it 50 times at many different places and make reasonable money right ?. Is this a valid concern.

2) I've seen a few sites float around selling systems which supposedly allow you to cheat at internet poker. The fact that they sell for $49.95 I think pretty much proves they can't be much good. However they do boast a method that allows you to see other players cards.

Is it possible they is some kind of security exploit in certian versions of windows that allows you to obtains another playes ipaddress and then gain access to their PC to view the output of the poker software they are running ?

Thanks for any advice.
