These e-mail messages from Germany might very well be the ones connected to the SOBER.U worm. DO NOT OPEN ANY LINKS IN THEM. DELETE THE MESSAGES!

Here is some info I received:

There is a new worm in the wild which when activated generates messages in German, with web sites linked in the message (these sites may be in English or German).

If any messages are received that appear questionable and you have not corresponded with the original sender in German before, delete them and do not open the web sites found in the messages.
