Internet stopped working

[Geneveve]

Hello everyone, I am having trouble accessing the internet through my computer (i am on a friends computer writing this). I had some adware on my computer, ntnuts32.exe or something, and followed some advice on another forum to get rid of it. Now my home page has set itself at about:blank and I cannot access the internet. WHats more, occasionally a strange website pops up that was remaniscent of the adware. Here is a hijackthis log, any ideas?
