Norton Antivirus 2010 Causes Corrupt Files

Norton 2010 is causing the files I am downloading to become corrupted.  I have uninstalled norton to confirm that norton is the source of the problem. When I download a file, it downloads and then norton scans it automatically. When I try to open or execute the downloaded file, it tells me the file is corrupted. I am using Windows 7 on a 64 bit Dell Studio laptop. I also have BitDefender running.
