Cause of fsav.exe return code 12

What is the likely cause of error code 12 in Windows folder?

 

Or put another way: how can we reproduce this error code in a test environment?

 

I get that the description for error code 12 is "Failed to open some targets, these objects may still be infected".

 

• Does this mean the file/folder is locked by another process?
• Does this mean that the file/folder did not exist at all?
• Does this mean that the file/folder was too large?

Here are the details:

 

Windows 2012

F-Secure version 14.55.111

Run FSAV.exe from .NET process

 

Turns out we had a threading issue, whereby the files in the folder were removed half way through the scan.

 

I'm guessin the FSAV process enumerates the files in the folder first; and then iterates over the list. We had a densely populated folder so this took a while.

 

Another process inadvertantly removed some of the files.

 

Thanks anyways.
