Norton AV locked up a file on my hard drive.

Hi, I'm new to this website, and I'm not sure where this topic should go; in fact, I find navigation on Symantec Connect to be the worst, and least obvious that I have ever encountered.  Plus it wouldn't let me change my password; what is "field {0} required"?  Actually, as long as I'm PO'd: when I find a new virus, that NIS doesn't detect, it won't let me submit it to Symantec via the quarantine.  I usually end up sending it to McAffee in a zip, because they actually accept and answer emails.  

 

Okay, my problem: I downloaded a 700mb .AVI video file that did not have a file extension on it.

I found that the file was locked, and could not be found or accessed by the system (WinXP-SP3).

It could not be deleted or renamed either.  File-unlocker couldn't access it either.  So, I renamed the folder it was in, and made a new folder of its previous name, and moved my stuff to the new folder.

At some point, I found the file in NIS 2005's quarantine.  It had been flagged as a virus.  I restored it, remembering after the fact that I had created a new folder.  So, I got the lost .avi file back in the new folder, but the old locked file is still tying up space in the old folder.

How can I get rid of it short of reformatting my entire hard drive?

 

Thanks,

Fraydo
