Hello and thanks in advance...

System details below
These 'entries' are in my registry along with about 60 others, quite similar.
I have, probably improperly, uninstalled Spybot 1.6.2 and SpybotSD2.
I wish to re-install 1.6.2 and use it.
I THINK that I should re-install/un-install each to clear up these entries BUT I am not sure. Please advise?
