Thanks, Hazelnut.
Sorry for the oversight - I run WinXP sp3; primary browser is Firefox, but I occasionally use IE; in both cases, latest stable versions.
I've seen a lot of links along the lines of the ones you kindly suggested, but they don't apply here - the toolbars were removed according to the vendor's instructions, and don't appear in the browsers. CCleaner shows remnants under Cleaner --- Applications Tab --- Internet, along with Sun Java. Come to think of it, it also shows Windows Live Messenger, which I uninstalled as per MS instructions (CP Add/Remove, just as with the toolbars).
I know this isn't any fault of CCleaner, but I'm hoping there have been enough others who have run into this that the knowledge (of how to get rid of those remnants) might be floating around.
I'm perfectly fine with using regedit; poking around the registry doesn't yield, to my eye, clear indication of what I can remove. Any ideas?
Again, thanks --- Dave
