if you are not using msn messenger, i suggest to complete eradicate it from your system for security reason.
create a text file with these command lines:
-----------------cut here----------------
@echo off
echo Removing Microsoft Messenger...
rundll32 advpack.dll,LaunchINFSection %WinDir%infmsmsgs.inf,BLC.Remove
echo Disabling it from running in the future...
echo REGEDIT4>%temp%
omsngr.reg
echo [HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftMessengerClient]>>%temp%
omsngr.reg
echo "PreventRun"=dword:00000001>>%temp%
omsngr.reg
echo "PreventAutoRun"=dword:00000001>>%temp%
omsngr.reg
echo "PreventAutoUpdate"=dword:00000001>>%temp%
omsngr.reg
echo "PreventBackgroundDownload"=dword:00000001>>%temp%
omsngr.reg
echo "Disabled"=dword:00000001>>%temp%
omsngr.reg
regedit /s %temp%
omsngr.reg
----------------cut here-------------------
save it and rename it as .bat, then double click.
