You should now set a new Restore Point to prevent infection from any previous Restore Points. The easiest and safest way to do this is:
Go to Start > All Programs > Accessories > System Tools and click "System Restore".
Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the Restore Point a name then click "Create". The new Restore Point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
Go to "Disk Cleanup" which can be found by going to Start > All Programs > Accessories > System Tools.
Click "OK" to select the partition or drive you desire.
Click the "More Options" Tab.
Click "Clean Up" in the System Restore section to remove all previous Restore Points except the newly created one.
Empty the Recycle Bin
