Error in Excel - Virus scanner has detected a problem with file


I am getting the following error when trying to open any Excel files on a WinXP Pro SP2 w/ Office 2003 SBE:
the file cannot be opened because your virus scanner has detected a problem with the file

These same files open fine on other computers, the problem seems to be limited to this one PC.

Here is what I've tried:
First did a system restore to a date prior to when the problem started
Uninstalled, Reinstalled Office
Uninstalled Office, Uninstalled Symantec AntiVirus (Corporate Edition Client)
Reinstalled Office (did not reinstall SAV) - same issue

The PC is clear of viruses and spyware.  

I have already found the MS KB article, but it wasn't of any help.

We are also getting the following errors in Word (problem occurred at the same time):
"The file already exists.  Do you want to replace the existing file?"  
"The file file.doc is not available" - file.doc name of test file

I've tried what I've found in ExpertsExchange Question ID 20893134, but nothing worked:

Any info on either or both would be greatly appreciated.

Thank you,

Re-save the file on another PC to a new filename and try again.

Also, if you are getting "The file already exists.  Do you want to replace the existing file?" that sounds like a macro virus to me. I could be wrong though.

I uninstalled Office 2k3 and installed Office XP as a temporary measure, it worked fine.  I then did a complete format / reinstall.  Everything is fine now. Thank you.
