It's slow in the hoos and I'm at work and it's slow here too, but it's not just the internet, it's everything, to open the start menu takes 30secs!!!
Do what SSK said and check the processes. Click the wee bit that says CPU to find whats using most of your CPU power and end them. Nothing should be hogging your CPU if you are not doing anything.
It was Windows defender that was conflicting. I'd rather have AVG although don't switch of WD firewall, just the anti-virus. It seems to scan every single file that appears including cookies. (happy to be corrected by an IT geek bod)
ctrl+alt+del > Processes > Click CPU > If your not doing anything and somethings using 95% of your CPU end it and google the name to find out if its a virus and how to remove it specifically. System Idle Process isn't a process its just what power your CPU's not using.

True that rootkits will not show up in processes. Malwarebytes has a rootkit remover as well now although is is only in beta stage and could have unpredictable results. http://www.malwarebytes.org/products/mbar/
What a bunch of fannys I had the exact same problem on my daughters netbook with AVG too. Go to C:/windows/system32 open that folder and delete everything inside. Reboot the netbook and Boom nothing
