That's how the message looks like:

However, once you're infected there is no way yet to clean the computer (no, not even with G Data^^). Even if your AV says it removed or put it under quarantine there will probably still be infected, undetected files.
However if you have (or think you had) this trojan on your computer, save your private data on a different HDD (it is important that you only save such things as movies, pictures etc. no .exe, .bat files) and reinstall Windows. Once you did this, you have to change all your passwords.
If you want to check if you have this trojan on your PC, download this tool and scan your PC:

But even if it says it removed the trojan, there is a high risk that some files are still infected so you should reinstall Windows anyway.
But it would be better if you just do not open the link anyway. ;-)
I hope you guys will be carefull.
