How do I uninstall Tuxera NTFS?
The uninstall button runs the following script, located at

/Library/Filesystems/fusefs_txantfs.fs/Contents/Resources/Support/uninstall-package.sh


#!/bin/bash

if [ "$0" != "/bin/uninstall-for-real" ]; then
    echo "Reexecuting script from memory."
    /bin/bash -c "`cat \"$0\"`" "/bin/uninstall-for-real" "$@"; exit $?
else
    echo "In-memory execution active."
fi
