is a long but interesting discussion on the subject.
Worth reading and trying the tips:
I foolishly installed QuickTime six months ago, and when I uninstalled it, only parts of it left. The rest had to be removed, one piece at a time (and there were hundreds) from the registry, from the search files and folders section, even from Ztree.
I have spybot, and it shows two ActiveX files that keep returning after every reboot. One cannot delete them directly from spybot, but must first go into the registry and remove them manually, and then delete them from spybot.
at the next reboot they're back.
Ordinarily I'd ignore something like this, but it seems that if I leave them there over time more little bits of QT begin appearing, one file at a time.
Is there an easy fix (or any fix) for this, or is it necessary? Am I missig a key element here?
