You're welcome.
If it finds a key you don't recognize, you can double click on the entry in regseeker and it will open the native reg editor to that key, so you can see more about it. Also, it offers several options on a dropup (is that a word?) list from "action" there at the bottom, you can export it, delete it, etc.
I must confess that all I ever do with it is look for anomalous entries, then sometimes back them up and delete them, one baby step at a time. I don't know enough about the business to do much more than that.
No, never have had a wrong key deleted...baby steps...very afraid of that registry. It is unforgiving.
Should have mentioned earlier that ERUNT and NTREGOPT are indispensable for backing up the registry first, but I assumed you knew that. In case not, they are
here.
Edit: Sometimes regseeker finds a word buried up in some key which I don't recognize, like a startup key if I remember correctly. In that case I just leave it alone. I would rather have an unused registry entry than to take a chance. If it is malaware I would just leave it to the experts.
