AVAST FREE partially remains after uninstall in WindowsXP SP3

Unable to completely uninstall AVAST FREE on 2 of my WindowsXP SP3 machines. I have used the two uninstall programs specifically designed for AVAST to remove the extra files not removed during the Add/Remove Process. McAfee Multi-Access continues to identify AVAST still being present after several uninstall attempts.
Can someone please help with this issue? Thank you

Remove all leftovers manually.
