In short, it's not part of the OS. It is however a sign that the OS isn't being protected, up todate, running "extra" services or more...
Read and take steps to remove it as well as follow the OS update guidelines.

I use a system Monitor program that displays how hard the CPU is running, RAM usage etc. Recently, for no apparent reason the CPU will start running at 100% and not stop. When I do ctrl+alt+del, the program using the CPU is called gt.exe. When I try to end the program, access is denied. How can I find out just what this file is doing? When I restart my computer, it's not loaded automatically. Have done a search, all of the references to this file seem to be related to a virus, however I have updated my virus definitions, and scanned my entire system and also the file individually, no viruses detected. I'm tempted to delete the file, but afraid it's a necessary file. Can anybody tell me what this file does? "gt.exe"
Running Windows 2000, 512MB of RAM, AMD Athlon 2000+
