From the doc: 'For years you have been able to test your virus scanner with the harmless 'Eicar' test file. Using the just released 'Trojan Simulator' you can now test your trojan scanner in the same manner, using a harmless demonstration trojan. This is a risk-free way to see how your security software behaves in a real-world situation. When you run Trojan Simulator, you will be presented with a screen showing some informational text about Trojan Simulator. Clicking the Install button will install the demo trojan on your system. The demo trojan simulates a real trojan server by hiding its main window and writing an autostart entry to the registry. Clicking the Uninstall button removes the autostart entry from the registry and then unloads the demo trojan server from memory. While the demo trojan is running, you get a chance to observe the behavior of any installed security software.'
