Sean, I think there is a mixup on the words, or your intention is unclear.

You would like to scan the file from the target server before the user has
selected the file to upload?

The order of operations in this case *must* be:
1) User select the file by drag & drop to the VM
2) Upload occurs
3) Target server receives file and is able to scan it

Any other order, scanning from the target side, is simply impossible -- the
server can't scan a file it does not have, and Guacamole cannot upload an
undefined file.

If you're talking about trying to intercept the file *after* upload, before
the user can execute/see it, that's on the OS/target side, outside of
Guacamole's reach... Guacamole is simply uploading the file over the
defined protocol, and I'm not aware of a protocol that allows an uploader
to force the recipient to begin an AV scan after upload.
