Is Net Shield an Apple app? Why am I being asked to update it while I’m in safari?

No, it's not Apple. Your being pestered by a pop-up adware. You don't need anything of the sort.
No Anti-Virus software or so-called “cleaning” apps are needed or recommended for Mac OS. They can conflict with Mac's own built-in security. At best they will slow your Mac by using unnecessary resources and at worst will bork your entire system. Your Mac has all the built-in protection you need.
