Windows XP includes a service called Messenger. It is an utility used by system administrators who run networks.
This Messenger service should not be confused with Windows Messenger, the instant-messaging application in XP. They are unrelated and disabling Windows Messenger will not cure your present malware problem. Neither is Messenger service related to MSN Messenger - another instant-messaging application.
Several malware companies have found a way to access Messenger service from the Internet. If you do not have a firewall, they can run spam messages using Messenger Service on your computer. It will appear as pop-ups, just as the one you have shown us with the window heading “Messenger Service.”
To block the pop-ups, install a firewall, such as ZoneAlarm SE which is freeware, or one of the other free or commercial firewalls that are available.
Windows XP includes a firewall, but it is much less effective than ZoneAlarm or most other available software firewalls as it only provides coverage against intrusion and offers no protection against outgoing malware aps or trojans.
You should also disable Messenger service unless you are on a netwark that uses it. To do that, click Start>>Control Panel. Double-click Administrative Tools. Double-click Services. Scroll down to Messenger and double-click. Click the Stop button. Under Startup Type, select Disabled. Click Apply>>OK.
