Third-party uninstallers today
Nowadays, pure third-party
uninstallers (uninstallers that only
contain basic components -- that is
the watcher, logger, uninstaller, and
probably the analyzer) generally are
unpopular and are not needed anymore,
because:
Most software programs come with their
own uninstallers (which are generally
better and more accurate), Most
uninstallers are not entirely accurate
(most of them are known to leave
leftovers, which should be deleted by
uninstallers), There are many better
and safer tools that can be used to
replace uninstallers, Because of this,
to make uninstallers more
merchantable, most (if not all) of
today's uninstallers contain other
related tools (such as a cache
cleaner, a junk file cleaner, etc.)
Why the third-party uninstallers are
still used today:
More complex installed programs make
system changes that the authors
forget, ignore or are not aware. They
often integrate third-party components
with no thought of their
uninstallation. The competition to
release new software versions with
additional features leave the
uninstallation with a very small
amount of attention and testing. The
accuracy of the integrated
uninstallers commonly leave much to be
desired. The uninstallers that don't
contain a logger module are
aggressively promoted on the market
claiming that completely uninstall
programs (a task that is impossible
and even dangerous without monitoring
installation) Many programs are
bundled with all kind of add-ons,
spyware or not, that are intentionally
left on the user's computer after
uninstallation of the main program. At
this time-- when adware, spyware,
keyloggers, trojans and other Internet
threats appear every day--
installation of a software product
from an unknown source is a great
risk. When things go wrong with a
newly installed program, an
uninstaller with a logger module can
prove invaluable.
Além das informações da Wikipedia, lembro-me de problemas com o CleanSweep quando você alterou / adicionou / excluiu arquivos durante a instalação do software. Além disso, o CleanSweep verificou se os arquivos eram usados por vários aplicativos (como DLLs compartilhadas)?
