CTRL+SHIFT+ESC, then click the Processes tab.
In the list of running programs*, locate the malware file or files detected earlier.
Select one of the detected files, then press either the End Task or the End Process button, depending on the version of Windows on your system.

To check if the malware process has been terminated, close Task Manager, and then open it again.

*NOTE: On systems running Windows 95/98/ME, Task Manager may not show certain processes. You may use a third party process viewer to terminate the malware process. Otherwise, continue with the next procedure, noting additional instructions.

In the left panel, double click the following:
HKEY_LOCAL_MACHINE>Software>Microsoft>
