I use Yahoo Instant Messenger.  I have checked not to receive any
messeges from anyone not on my "friends" list.  Lately, I have gone
back to my desk to find absolutely tasteless boxes in the middle of my
screen no matter what program I am in.  These boxes say Messenger up
at the top but they are not regular IM messenger boxes that chat back
and forth. They are gross advertisements.
I have a screen shot of the last one from something called
growlarger.com.  I want to send it to Yahoo because there is no way to
respond to this box other than click on the links or close it.  I do
not want to go to the site because it will open the door to more crap.
 
Question:  I cannot find any sort of an email for Yahoo to send this
to.  Do they have any sort of regulation for their IM or do they just
throw us out there to be spamed by the worst of the worst?  Can you
find any sort of Yahoo place that regulates their service to contact
by phone or email?
My name is Carolyn but when I open my yahoo email it says "hello Walt"
 I would also like to get this corrected.  I can find no email or help
to solve this problem.

Hi! Thanks for the question.

This is obviously a violation of the terms of service (TOS) of any
type of Yahoo community and could be reported at the following form
page for Yahoo (Terms of Service) Member Conduct Page. After filling
the boxes, it will immediately email Yahoo and alert them to your
complaint. Don’t forget to put your email address so they could
respond back to you.

Just what I needed. THANX

Are you sure they have anything to do with Yahoo at all?  The reason I
ask is every morning when I wake up and check my computer, I have
three or four of those things, boxes with ads that say "Messenger" at
the top, and I don't have Yahoo Messenger.  I was sort of under the
impression that it's related to some function built into Windows,
which the Windows people put in thinking it would be useful, but about
2 months ago people figured out how to use it to send spam instead, so
maybe Windows will put out a patch soon enabling people to turn that
function off...

Maisie is correct. The pop-ups you are seeing have nothing to do with
Yahoo (or MSN) Messanger. Here is an article that explains these
pop-ups and how to get rid of them:
