eZula.TopText

Hi, my only problem is that Microsoft AntiSpyware is
unable to permanently remove this ezula.toptext thing.
Its finding it every time in the same locations
(HKEY_CURRENT_USER\software\DR_S and another spot with a
bunch of numbers that i dont want to type out), and its
able to "remove" them, but they keep returning.

Anyone know anything about this, or could help me perhaps?

Thanks in advance.
