WordPress Zip File is Corrupted?

Hi,

I just downloaded WordPress version 3.0 in my desktop yesterday and uploaded it to my website. Everything seemed to work out well yesterday.
But this morning when I turned my computer on, Windows scanning just
turned on automatically and I get this error:

File C:RECYCLER\ S-1-5-21-746137067-1035525444-1801674531-1003\DC 40.zip|>wordpress\wp-includes\widgets.hp error 42125 {zip archive is corrupted}

Can you tell me what to do and if this error has put my website in danger??

Thanks…
