I stumbled upon an application called Big Top on my macbook pro 13 inch earlier today. This is after I have been having problems connecting to my schools network, the IP addresses are completely incorrect and the new leases keep on giving me the wrong address...the IT guys are completely clueless as am I since I am fairly recent switcher. So is Big Top some kind of a strange virus that could be causing this. It says it is made by Apple but I know some really strange things can happen. I would really appreciate any kind of help on this entire subject matter. Thanks
