Cannot save a file that I create

[Arnold]

When I create a new file and I want to save it, it does
not give me the opportunity to name the file. Therefore
it does not save. Excel was working until a couple of
days ago. I reinstalled Excel and it still does not work.

There was a virus that affected the File|Save, File|SaveAs and File|Open.

maybe you got hit.

If this isn't it, do you get error messages?
