A way to possibly do what you want to do is to duplicate the file handle, and 
to hack on ClamAV to scan a file given a handle to it.

On unices you can open a file, hold a handle to it, and then remove the 
directory entry (rm file) -- the file will exist on the disk without a 
directory entry, for as long as the file handle is open. I don't think you 
could do that under e.g. Windows, so Unix is different here.

In general the only way to get at a file knowing its handle is to use a 
duplicate handle. That'd be the only robust way AFAIK.
