Has anyone heard of this?

Ouch! Last evening when running Webroot's spyware program (forgot what-it's-called) it detected a spyware "Amecisco Keylogger", and gave a description that it was a stealth spyware that records keystrokes.

So I went to run the procedure to quarantine and remove, but when I do the Webroot software says "skipping step 2", which is the important quarantine part. So the software is detecting it, but not letting me remove it!

My question is, why is this happening, and any ideas how I got it in the first place? I don't open email attachments, and my wife only knows how to open Solitaire...
