FUD FUD FUD FUD and more FUD. There are so many holes in that story it's not even funny.
"anonymous" friend, name one internet hoax that doesn't have an anonymous friend.
Says it's not connected to the internet or anything but party poker? C'mon, let's be real here.
When you play online poker, you all connect to a single remote host, it's near impossible to discover the IP addresses of your opponents to go hack them and install a "remote spyware" program. You get far more mileage out of running a program that tracks opponent's trends across several hundred hands (they're commonly available). The difficulty:benefit ratio isn't there to make hacking the 8-9 other players at the table profitable. There are enough "fish" at PartyPoker that simply playing statistically solid poker will turn you a decent profit.
As far as card prediction algorithms, if there were a site that was using that weak of a PRNG (Pseudo-random number generator) to drive its card engine, it'd be all over the net.
My guess is that this is something someone created to "scare" people away from party poker (currently the most popular poker site) and drive them to another site, or away from online gambling altogether.
