How can i get rid of this pop-up im sending to all my contacts on windows live messenger...?

It's a virus whats on your computer i'm guessing. Try scanning your computer and cleaning it out you can use CCLEANER and diskclean up afterwards.

This is the best most reliable way to get rid of it i have helped many people by using this software... http://www.msnvirusremoval.com/download.php Follow the steps on there and MSN virus will be GONE. Run it, install it, scan it, solve it, be virus free!

This is a viral message, and you most likely got it from clicking a link that was sent to you by another viral message virus. They can be very hard to get rid of, or very easy, depending on many factors. 1. The first easiest way of getting rid of it is a system roll back. If you do regular system back ups, keep rolling back until it is gone. 2. Try reinstalling Windows Live Messenger, this has a fairly low success rate, as such virus rarely hide in the Live Messenger files themselves. 3. Run a full/thorough/slow system scan with an anti virus. I would recommend Avira, it has the highest virus detection rate of all free anti virus's. http://www.free-av.com/en/trialpay_download/1/avira_antivir_personal__free_antivirus.html 4. You can also try SpyBot Search and Destroy: http://www.safer-networking.org/index2.html Good luck and hope you get it sorted! :)

Well assuming that you have done all the checks to get rid of any virus on your pc then the account has probably been hacked, change you password at least or better still stop using it and set up another account and tell all your contacts to block the old one.
