Spyware program, Win32.NetAngel, performs a variety of functions but is characterized as a backdoor Trojan.  Its author, StTwister, released this nuisance onto the public in August of 2004.  Written in Delphi language, Win32.NetAngel is no angel.  Its abilities should be cause for great concern as it will be able to turn on and turn off your computer, activate the screen saver, empty your recycle bin, log your keystrokes and much, much more.  Once it enters, it will embed itself into your system’s registries under random and cryptic names making it very difficult to detect.
