excel documents automatically opening...

I recently purchased a new computer with vista ultimate. I installed my office 2003 and it mostlly runs correctly. One major problem that I have with it is that (mostly) on start-up it will automatically start opening excel documents. It is not just one or two documents open, but more like 70-80 and sometimes the only way to get it to stop is to force a shutdown. Does anyone have any ideas of how to resolve this? It is really getting frustrating. You can't do anything while it is opening these documents.

Thanks,

Is it opening the same document?
Are these documents in your startup folder?

It actually opens up a new document in each of them. They are blank and have a number assigned to them like doc 1, doc 2, etc. I still have not figured out where everything is located so I am not sure where the start folder is within vista.

If it does not help run a malware check, this does sound suspisous.
