Select all the files in the folder (ctrl-a) and press the delete key. Answer yes. It's possible that some files are in use and will not delete - in that case, use the ctrl key to deselect each single file that won't delete and keep doing that until you've delete all you can.

You might also try to stop some running processes, but in the case of this Bad Boy, they can be hard to know which to delete.
You might see SVCHOST.EXE, Demo.exe, and security.exe. I'm not sure which operating system you're running, but ME or 98 won't be likely to have any of them as normal processes.
