An hour? You can paste text using ctrl - v.
Anyway without knowing what your operating system and service pack is it's not easy to advise youi but the first thing I would try is to go back to before this all started using System Restore.
Try Stinger and Malwarebytes Free, maybe even RootkitRemover just in case, all linked in the last link in my signature below.
If the problem persists try posting a Hijackthis log, not here, but as instructed further down that link.
The pop-up is a clue : a Fake AV scareware program. Not sure about the "radio" - sounds like an audio file got downloaded and is running.
Yes, a System Restore should do it.
