Is there a definitive book or site that gives full details of the Windows 2000 Professional registry with clear descriptions/options for each key? Can you use the registry to be SURE that there is not a back door installed?
Yes, you can check the Run and RunOnce keys in the registry to see if a program is running that you don't know about. But doing so doesn't ensure that a back door isn't installed. There are many other ways to install spyware, and the registry is just one of them. I'd consider using software such as Ad-aware from LavaSoft.com to snoop these plagues out.
