The Subseven Trojan, sometimes called Sub Seven, installs itself onto your computer and modifies your system registry so that the program runs every time you turn on your computer. The Subseven Trojan is particularly dangerous because the virus opens a backdoor to your computer, which can be used by remote hackers to download additional malware and steal your personal information. Note that the removal instructions apply to the Windows 7 and Windows Vista operating systems.
Press "Ctrl," "Shift" and "Escape" simultaneously to open the Windows Task Manager.
