Hello all my computer was acting very messed up and was being bogged down by spyware and browser hijackers so I completley emptied my computer and I uninstalled and reinstalled windows xp then I installed all of my updates and then installed norton 360 and a pop up stopper from panicware.My internet is through cable by mediacom and for some reason my computer is still running realy slow coming on to the internet and when I open my email wich is also through mediacom.What did I do wrong and what can I do to fix this.All help is much apreciated cheers.
