rundll32.exe file purpose and description:
Rundll32.exe is a program which would have been on your pc since the day you purchased your pc. Always verify the exact disk location as many virus and spyware writers will attempt to fool you by using a similiar name or same name in a different location. This file is part of the Microsoft Windows operating system. Rundll32.exe will actually execute functions in DLLs. If you are deleting files on your computer as a spyware removal protection method, then note that this is a required system file. Note that rundll32.exe can also be running many different other DLL or EXE programs, so you may want to check the programs listed after it in your startup list also, as these may be executed by it. Rundll32.exe is considered safe and is not spyware, adware, or virus related and does not need to be removed. (See the details below for the actual location of this file.)

Be aware that many tasks will be similiar names to existing tasks or processes.
You can always view the running tasks on your computer by pressing ctrl-alt-del to view the windows
"task manager", and then view the "processes" tab. This will show you all tasks running or currently active
on your PC. Although this shows you all running tasks, it does not show dll file thats are loaded, as they
get loaded as part of other processes. Many spyware writers attempt to hide their files
on your computer, for example, rundll32.exe may be intentionally misspelled to look like a similiar task, or spyware may be named very
similiar to a Windows system task. The reason they do this is so you cannot easily recognize the name in your tasklist
as I have mentioned above. Make sure always check the location of the file if you are concerned.
