While my eyes are closing rapidly... my first thought is

CHANGE YOUR PASSWORD!!!!!!

After that...

Turn OFF system recovery, boot to safe mode, uninstall the software if you can from safe mode, run a spybot checker and your antivirus scan and scan ALL FILES, because from the sounds of it, you have spyware somewhere on your system and also that your PASSWORDS (note the S) have been compromised.

Do this if you can, then once you have and get back to the normal desktop, try reinstalling the software...

If ANYONE has been to any of the following sites on your computer, you more than likely have spyware and/or a virus

Porn sites,
crack sites
hacker sites
shareware sites generally located outside the US (not to my knowledge tucows.com or cdnet.com )
any site where you try to circumvent the normal legal process for purchasing/downloading/registering software

If all else fails, you can try creating a new user account and give it admin rights and work from that one...

Keep me informed to what you find and maybe i can come up with some more ideas

I have the same exact problem. I tried doing the Mc Afee site advisor thing, but it tells me it cannot save the changes.
What else can I do?
Plus, I tried going back to the old msn messenger version, but it keeps on popping up the new version telling me I have to install that or else cannot sign in!!
I have tried using msn messenger 9.0 (new version) on another pc and the webcam runs prefectly... help!!!

The Problem with windows Messenger is not with your Anti Virus or McCaffe or Norton, it is a malware bot that attatches itself to the MSIN.EXE file that runs Email and Messenger, Your Anti Virus and Firewall programs allow it to run as you have Messenger allowed privillages to run in your Firewall program, This Virus on Msn Messenger, actually overwites the Messenger lib files and gives the illusion that messenger works fine, which it does, but the original file that came with MSN Messenger has been deleted and replaced with this Virus One.

TAKE NOTE!! GO TOO LIVE MAIL WEB PAGE and change your password there, DO NOT USE MSN MESSENGER PROGRAM TO DO THIS,

This will illiminate The problem

Or if you Wish to be sure and go further...

Uninstall The Version You have of MSN
Then after that...search MSN and search Messenger on your computer, this bugger of a file will leave remnances in folders and pieces left over after install...so find anything to do with MSN and MESSENGER and delete the lot off your computer, delete the messenger cache Then once done, turn off SYSTEM RECOVERY...and Reboot

Then Turn On System recovery and Install a new MSN Messenger. then TAKE NOTE!! GO TOO LIVE MAIL WEB PAGE and change your password there, DO NOT USE MSN MESSENGER PROGRAM TO DO THIS,

Then when complete, open your new MSN Program, Dont Tick (AUTO SIGN ON) enter your password manually for about 10 times when you log in.....THIs Stops it all.

Microsoft are aware of this malicious Spam Bot attaching itself to promote porn sire advertising and have created a Clean tool and malware remover specifically designed to hunt down and remove known component names this Virus uses, it is called "Clean Virus MSN"

Well, I had the same problem a few weeks ago and it went away by itself... Leaving my computer on overnight, for at least a couple of days with windows live messenger signed in did not sign me out for a few weeks now.
After reading these posts.. im quite confused. So what could it be? Please answer if you know because I don't want to get hacked.
But otherwise, I guess just wait and see or make backup for your files if you are scared of losing or exposing your privacy. =)

Please help me finde a very important conversation on windows live messenger we wright for each other.
Thank you Maria

When i click on my msn it wont come on straight away when i click on it but i dont know why
