My IP is routing to wrong server

Seems like spyware to me, but every now and then when i try to go on I-Explorer, i get a 404 page.. and i know the site is up, i constanly have to dissconnect and reconnect... Seems to me that my ISP is routing my IP Address to wrong server... Could this be true, and if so how can i fix this?
BTW i do not have any P2P programs, and i just rencenly Formated my computer... But i do have a small home network and that computer has a P2P program.. Could the spyware on there, be afecting my computer?

What OS?
Check your Hosts file, it may have the page blocked / routing to 0.0.0.0
Worth a shot.
Does it do that to ALL webpages? Try deleting all the entries in your hosts file.
C:\Windows\

i reformatted my computer 2 times already, and im not the only one that gets this. alot of my members get this error also.and it only happens to this site

Are you talking about when trying to log onto your homepage? Cuz I get 404 with it also..

i get 404 or redirected to wrong website sometimes.....weird, but restrating comp always fixes it

There is a Worm-like virus that attack Backbone, Router and all that stuff maybe your problem is related to that.
