Okay, no problem if the addons are gone. And if the entries for the processes I listed are already unchecked on the Startup menu, that's okay too.

If the problems have been resolved:
Removing all of the tools we used and the files and folders they created

• Uninstall ComboFix and all Backups of the files it deleted
• Click START> then RUN
• Now type Combofix /Uninstall in the runbox and click OK. Note the space between the X and the U, it needs to be there.
  

• Download OTCleanIt by OldTimer and save it to your Desktop.
• Double click OTCleanIt.exe.
• Click the CleanUp! button.
• If you are prompted to Reboot during the cleanup, select Yes.
• The tool will delete itself once it finishes.

Note: If you receive a warning from your firewall or other security programs regarding OTC attempting to contact the internet, please allow it to do so.

• You should now set a new Restore Point and remove the old restore points to prevent infection from any previous Restore Points.
• Go to Start > All Programs > Accessories > System Tools
• Click "System Restore".
• Choose "Create a Restore Point" on the first screen then click "Next".
• Give the Restore Point a name> click "Create".
  
• Go back and follow the path to > System Tools.
