your CPU has a virus... (nothing harmful to data)
I've had the same prob with certain sites loading UBR slow :/
I've made a guide on my forum that tells you how to keep your cpu virus free without VPS...
(I'm doing it)
but it can be used to clean your PC as well...
I don't rmbr the link off-hand, and I'm on my Wii right now... :/
once I get net on my cpu
(when my bro turns his cpu on)
I'll find the DL for ya
