disable U3 support

We aren't using WINSCP yet...I have recommended it but our security person wants to know "if U3 support software can be removed" before she will approve for us to use it. Is this possible and is this really an issue? We will be installing it onto our computers not onto a USB drive. Thanks!

Not sure, what they refer to. There's no U3 support software.
WinSCP was available as U3 package years ago. But that's no available anymore as U3 itself is gone.
