Using the Process Monitor from AATools, you will see whether any foreign programs are running on your computer. If you find some unwanted program, you can terminate it by clicking the 'Terminate Process' button on the Toolbar. Using the AATools Network Monitor, you can see what ports are in use on your local PC for connection with remote systems (LAN/Internet). On Windows NT/2000/XP the Network Monitor will display you the services that are active on the ports, and map the ports to their respective applications. If you register port probes directed against ports that are normally not used, it is possible that someone is trying to connect to a Trojan inside your network. Using the Registry Cleaner (Startup section) from AATools, you will see the list of programs that are registered under Run, RunOnce, RunOnceEx and RunService registry keys. So you can find out what programs are started behind your back. You should check these programs to see they are legitimate ones but not Trojans programs.
