Internet Download Speed Slow On Computer?

This is my first post/thread on TH.Anyways, I Just recently bought a laptop for HS, about half a month old. Everything Ran fine , Until My computer decided to not work anymore.

I did a system restore from a repair disk and fixed, the only catch, norton reinstalled. I had uninstalled norton and when I did a system restore, the program probably sent it's server a "scam" alert as the program didn't respond after, So I had to uninstall it manually, removing the files and all the registry entres. Now, week later, I notice that my computer is downloading EPICALLY slow. My speed is 11mbs, on my alternate computer, it will download a 11 mb file in less then a second, but on the laptop, 25 minutes? No way is that possible.

I did some registry scans, with wisecare 365, fixed the registry and download time has come down to 13 seconds, which is still crazy long,
