Use System Restore and choose the earliest Restore Point possible.
If you have a registry backup, you can just use it to replace the current one. ERUNT can do it in XP. It is a freeware.
NTBackup is a builtin XP PRO (only) program that can back up system state.
Have you tried System Restore? Accessories->System Tools->System Restore.
Screwing with the registry is tricky and dangerous. Before doing anything yourself, download a trial version of a registry cleaner/defragmenter like the one that http://www.3bsoftware.com offers. If you are lucky, the anti-virus software will have rendered the viral registry entries useless and a simple clean will take care of it. Good luck.
delete the client registry blob, manually restart the comp. and your good to go.
Restoring the Windows XP/2000/2003 Registry
Option 1:
Click on Start, then All Programs, then Accessories, then System Tools, and then click on Backup. If you do not see the Backup utility you will need to install it using your XP or 2003 CD.
When the program launches, if you are not in the wizard, select the Backup Wizard Option.
When the Wizard opens press the Next button.
This screen will list all the known backups that were done previously. Select the System State backup that you would like restored.
Press the next button and then the Finish button.
When it is completed you will see a report of the backup. You can then press the Close button and then exit the program.
Option 2 (Only for XP and 2003):
Insert your Windows CD into your computer and reboot.
When it prompts you to "Press Any Key to Boot from CD", press any key.
When the screen appears that gives you the options to Setup, Repair or Quit, press R on your keyboard to enter repair mode.
At the next screen select the installation of windows you would like to work on. For most people there will be only one option.
When prompted enter your administrator password and press enter on your keyboard.
When you get the prompt, type cd repair to enter the directory where a Registry backups is stored.
Type the following lines, pressing enter on your keyboard after each line:
copy default c:\windows\system32\config
copy sam c:\windows\system32\config
copy security c:\windows\system32\config
copy software c:\windows\system32\config
copy system c:\windows\system32\config
NOTE: If it prompts you to overwrite the existing files, select Y for yes.
When you are finished, type exit and press enter.
Remove your Windows CD and reboot.
