For the past month I have been plagued by a popup that appears on my on my screen sometimes two or three times a day every day. This is a small box with the words "Messenger Service" on top and coming from "Systemcheck" saying that there is a breach in my computer security and to press OK and follow the Url. Up till now I have just deleted the message, but I am getting fed up with it. can anyone suggest a good program to download,(pref. free) to get rid of these things automaticly. By the way the message is in German.
