Okay, so I downloaded the program and figured out which svchost.exe process is taking up the most memory - I've opened up the services tab and see a bunch of processes. Do I just figure out what's what and um...disable some stuff or something? Sorry, I'm a bit lost here.

I do see RasMan (Remote Access Connection Manager) is controlled by this process - is that a possible hijack? Ah, windows auto updates is also part of this. Should I disable it? If it would help, I can also let you know what else is running as part of this process.
