aaaaah, hoaxes
Ignore the e-mail that tells you to delete the file.
The file is in fact part of a standard windows distibution. Almost everyone that recieves this e-mail will have the file.
All e-mails like this are hoaxes. If you goto a website like McAfee's, they also have details of hoaxes, as well as actual viruses, which can be helpful.
I imagine someone finds it funny, and so starts these things, I just find they clog my inbox, I just hit delete.
