Removing Adds Using Windows Settings:
Go to the Start menu and then select Control Panel and then select Internet Options. Select the security tab and then click on the Sites under restricted sites. Now add the URL rad.msn.com and there will be no ads and it will not be able to bring ads to your messenger any more.
Open C:\Windows\System32\drivers\etc and locate file named as hosts. Windows doesn't know which program to use to open this, so select the Notepad from the list of programs and click Ok.
Come down till the bottom and type the following in the host wp-content/uploads
Now save and exit and restart the system to let that the changes can be taken place.
Remove Ads Using a Freeware Ad Blocker Application:
If the above manual ways are not working for you then simply download any third party free- to-use utility that you may find on the internet. Here are some of options that you can try:

Live Advert Remover:

This is also a free utility that enables you to remove ads from the Hotmail Messenger, but not that wildly use.
