Trojan Slayer is a software program that helps to protect your computer from Trojan infections. It learns what programs you use on your computer, creating a list of "good" programs. Once it has learned what programs are acceptable on your computer, you can switch to one of several enforcement modes, where it runs continuously. In these modes, Trojan Slayer blocks or eliminates any program that it has not learned is a good program. Since Trojans are just programs, this provides constant protection against ANY unknown program. There are four enforcement modes: 1) Report- In this mode, Trojan Slayer will pop up a screen informing you of any unknown programs that are running. You can ignore the new program, have Trojan Slayer learn it as a good program, shut down the new program (cause it to stop running), delete the file from your hard drive, or replace it with a dummy file that blocks further infection. 2) Block- Automatically shut down any unidentified program it finds running. 3) Delete - Not only shut down any unidentified programs, but automatically delete the file from your hard drive. 4) Replace - Automatically delete the file from your hard drive and replace the file with a dummy file of the same name. This is sometimes necessary because some Trojan files actually replace themselves if they are deleted. Replacing the file with a dummy file of the same name can block this replacement technique. Trojan Slayer is extremely flexible and easy to use. You can manually delete the Trojan from the list of "good" programs or add new software to the good list at any time.
