antivirus scanner choking on opened files

["J. Yoon" <supercool9000 () hotmail com>]

I might be getting nit picky here but here's a crucial point to be made...

I've opened several files in the same directory (different file types : MS 
Word, P2P, email, explorer, and photoshop) and then highlighted all these 
files to scan for virus.

Apparently, AVG virus scanner has no trouble scanning files that are 
currently being used
whereas Norton chokes on the same set of files and spits out the following 
message:

"Unable to open the file C:\test1.doc The file is currently being used by 
another application or you don't have permission to open the file. Click 
here to go to symantec technical support knowledge base 3019.2"

I haven't tested other vendors because I deinstalled them a week ago.

Unless there's something else going on here that I should know about, I 
think a good virus scanner should be able to scan ALL files ESPECIALLY those 
that are currently being used.
