Computer Virus Help Needed

Would it be erroneously optimistic to assume that the source can be traced?

To what end, because no one will do anything about it.
The problem is that this software can be purchased for use by anyone, and there is more than just one source.

The page where the link that was posted said if you called that 866 number they would remove the virus and give you a report on where it came from, but I certainly wouldn't trust that.
Probably just another part time college student employee asking for a CC number on the other end anyway. (always is)

One thing to note here is you will never always be ahead of infections targeting Windows, but you may spend the rest of your computer using days trying and worrying about it to the point that it's not worth it any more. :D
You see how hard the government and retail entities try and can't stay ahead of it, and they have WAY more resources to throw at it than we do and I am certainly not going to spend my days using it as if it were some sort of hide and seek battle with virus designers.

Windows is way too easy to reinstall to live like that, so you just don't keep anything on it that you can't afford to loose or have compromised.
