Method 3:

Use the program to find trojans and kill them, such as Trojan Remover v4.4.0. You can download this program very useful at: http://www.simplysup.com/tremover/ .

Every time Detecting a suspicious program, Trojan Remover will display a message box to alert you. It tells you the name of the suspect program and the archive folder and will remove the dangerous trojans from the system file.

Most other Trojan programs execute in MS-DOS because while you are running Windows, you cannot interfere with system files. With this program you will be more comfortable because when you find out in the trojan memory, the program will ask you to Restart the computer and will erase them. And especially the program is smart in that it automatically assigns Read Only attribute (read-only attribute) to system files.
