Hi,
I've this pop-up coming all the time saying that the registry on the machine is corrupt. This essentially is some spam as my system is working fine. The sites mentioned on the Message Dialog boxes are : http://registrycleaner32.com/ and http://wupdate.com and htttp://www.regfixup.com.
I've Spy-Bot and Zone Alarm installed on my machine and it seems they are unable to detect this I use FireFox so IE problems are ruled out.
Has anybody faced this problem before and how did you tackle it?

Thanks.

That sounds like Messenger Service Spam. Disabling the Messenger Service should fix it. Here are directions and a description.
