Hey
I just got a new toshiba laptop, and once I turned it on, it already had that "nt authority system blaster worm" problem, so I downloaded the security update from the microsoft website. Im not sure if the patch is cuasing this but, every time I turn the laptop on, it slows down the internet for the rest of the computers on the network, including that one. As soon as I turn it off, everything goes back to normal
Does anyone know what the problem could be?

This has also happend to me in the past on one of the desktop computers, and it was solved be reformatting the hd, but i'd like to try to figure out what the problem is.. I just got this laptop too.
