Hi,
That's wrong message from Antivirus.
All that files from plugins: Ninja Popup & Ultimate Addons for WPBakery Page Builder plugins.
As I asked author of that plugins before & Envato - they can confirm that's wrong scan. No any virus in that file.
For the update doesn't appears on your Dashboard, please try deactivate all plugins ( except plugins come from the theme and try it again ) - seem you have a plugin caused this issue.
Best Regards,
