rundll32.exe task 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.

If you are deleting files on your computer as a spyware removal protection method, then note that this is a required system file.

General information:
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.
