Thanks all.
I downloaded the "remove-spybotsd-settings.reg" file and saved it to my DOWNLOAD folder. That is why I was questioning how to 'run/execute' it.
I saw in previous post "Download and run the fix using internet explorer."
As usual, I got a bit confused about that, but then after thinking about it awhile I thought it just meant to download the 'reg' file while using IE. After downloading it (to my download folder), I could simply click on it to 'execute/run' it.
I've just heard so many stories about making changes to the REGISTRY and how it might ruin the compuer. I just bought this computer and would not want to ruin it with a wrong REGISTRY adjustment.
(I'm really a novice at all of this. Sorry!)
