STOP!

Registry Cleaner Recommended!

To fix the errors please do the following:
1. Download registry repair from http://www.regwincleaner.com
2. install registry cleaner
3. run registry cleaner
4. reboot your computer
FAILURE TO ACT NOW MAY LEAD TO DATA LOSS AND CORRUPTION!

First off go to Windows Update and load all Critical (Express) updates.

This will include SP2. The Messenger Service was disabled in SP2.

Next get a good firewall. The fact that Windows Messenger Service is being exploited indicates that your computer ports are open to abuse.

k ill do that thanks
