What is Xposed Installer? I downloaded it from here:

When I install and open it, Norton Security showed a dialog box saying “Norton Security has discovered a malicious file and will help you remove it.” It called the file “Xposed Installer”
My phone crashed and rebooted with the dialog box still open. When I relaunched Xposed Installer, Norton did not show the dialog box again.
