does the bootable CD version malware scan and virus removal include the XP system restore points ?

Does the bootable CD version malware scan and virus removal include the XP system restore points ? Or on this 2005 Dell XPS 400 model computer with XP Media Center, which we just ran a long and sucessful scan and removal on, should we turn off that system restore and then re-boot to remove previous restore points or not needed ? Also that PC has a separate partition on the hard drive for automatic back ups which may also contain copies of the malware that were deleted on the C: drive partition.
