If so, then you are using an older version or (un-updated) of Windows (pre XP SP2). These type of popups exploit the Messenger Service in your Windows OS, which after XP SP2 is disabled by default. SP2 is far more secure and will protect you against lots of threats.

A popup blocker “thingy” will be of no help in this case.

You have 3 choices to end the problem.

1. You can disable and stop Messenger Service by typing “services msc.” (without the “”s) into your Run Box and then disabling and stopping Messenger Service.

OR

2. You can use the free utility called Shoot The Messenger to automatically disable this unnecessary service.

OR (Best Solution)

3. Update or upgrade your operating system to at least Windows XP Service Pack 2 (SP2).

Please note that Windows Messenger Service is not the same as any Instant Messenger program that you may have on your computer. Disabling it will not cause you to lose any IM functionality that you may have.

Also, your computer is NOT properly firewalled. A firewall would also stop this Messenger Service spam.

Good luck
