You are apparently quoting from
this article about using Regedit. Editing the Registry as described there and cleaning up the Registry from a malware infection are two completely different things. If you are trying to recover from a malware infection, forget about editing the Registry with Regedit. Consult one of the numerous articles at Gizmo's that explain how to deal with an infected computer. One is
How to Clean An Infected Computer.
If your restore point was made before the malware infection occurred and if the malware didn't infect your restore points (don't count on it) a restore point
might help but I wouldn't bet on it. If you have a complete system image made before the infection that has been stored somewhere not connected to your computer, that might fix your problem. But generally you have to go through the type of tedious routine described in Chiron's article.
