“Yahoo Messenger is not installed on your machine” popup

Posted December 27, 2008 

“Yahoo Messenger is not installed on your machine” popup is a worm that spreads through, you guessed it, Yahoo Messenger.

If you have it on your computer, you will see the following message:

“Search result: Yahoo Messenger is not installed on your machine
Going to install it”

This worm searches your computer for Yahoo Messanger so it can send itself off to your contacts. If you don’t have Yahoo Messanger, it will install it for you though I don’t know who it will send itself to.

If you see the popup on your computer, it’s time to shoot the messenger and remove “Yahoo Messenger is not installed on your machine” popup.
