don't do it. If you do, the entire internet will disappear.....for everyone.......ohhhooohhh.
I also believe the boogyman is right behind you.
If you have broadband, and you had to install the crap software the first time to set up your account. If this is what you are worried about, don't. Your account is still with your ISP. In fact, you don't even have to install that crappy software this time around.
Oh, and watch out for those darn leprechauns....
