Yahoo toolbar was installed on workstaions on our LAN. After uninstalling the program I find that windows registry was modified and client downloads are blocked. How do I reset registry?

My computer was infected with the w32 trats virus on December 28th. I have Norton system works and norton internet security, but it got around it apparently. My research showed that the virus has been around since the beginning of December, but norton didn’t have protection against it until december 29th–the day after I was infected. Now I am wondering if there is a better protection out there.
