Trojan.Win32.KingSolaris or KingSolaris is a trojan that runs on Win32. It is more dangerous than regular trojan viruses.
After being clicked on twice a message box appears with the title "xxx screen-saver". If the user follows the instructions, "Click above", the trojan runs the Delete command, and deletes C:\Windows. This prevents the system from booting up because C:\Windows contains important files, such as System32.
