 You're wrong there, lets look at Yahoo Messenger:

yupdater.exe

The above little executable stays in the default Yahoo Messenger directory
and can modify any files within that directory and sub-directories, the
yupdater.exe can create and delete any file in those directories, and has
the power to create new files and folders on the command of Yahoo. At no
time is there notification by Yahoo to the end-user. I've witnessed when
Yahoo were testing their backend anti-spam system, that blank folders were
appearing within the default Yahoo Messenger directory. If an attacker can
hack Yahoo and control everyones yupdater.exe then Yahoo will turn into a
very dark place.

Here is another executable that does discrete little directory updates to
your system without end-user interaction or notification:

YServer.exe

We tried to protest what Yahoo was doing other the years in private, and
even thought at one point about putting out trojan horses and viruses under
the same file names so Symantec etc would flag them as malware, although we
didn't

So yeah, Yahoo have the ability to and do infact modify your system
without permission :)

This is done randomly at Yahoo's own discretion and is seperate from
legitmate announced Yahoo Messenger updates :)

Its about time Yahoo came clean about yupdater.exe and YServer.exe instead
of anonymously sending commands to operating systems, to modify, delete and
create files and (or) folders without anyone knowing.

No one is saying Yahoo is doing anything evil, but what if an accident
happened? Yahoo would get its ass kicked

No one can say what unexpected modifications to folder and files might do
to individual end-user systems.

Yahoo, sort yourselves out.

Foul play
