Juha-Matti has pointed out an interesting Trojan.Spaxe. The interesting part is that it will display a balloon message, attempting to fake from the Windows Automatic Updates icon on the System Tray, with the following text:
Your computer is infected!
Windows has detected spyware infection.
It is recommended to use special antispyware tools to prevent data loss.
Windows will now download and install the most up-to-date antispyware for you.
Click here to protect your computer from spyware.
Clicking on the balloon will result in downloading a file from the Internet.
If you have got this message, don`t click to the ballon and check your computer for spyware now.
