I've used Norton for at least 15 years, and am REALLY annoyed with the latest version of Norton Security for Mac.
For the benefit of other who have used the latest version of Norton Security for Mac...
It all started when the NFMwps service suddenly stopped working (throwing errors for the extensions / add-ons in browsers) and the only way to fix is to uninstall and reinstall the whole damn product. (Through the Looking Glass into the realm of MS Windows).
1) download #2 (1st re-install): didn't fix the problem & only way to stop the Live Update (after 200+MB) was to crash the Mac
2) online support: need to use the special Norton uninstall utility, and THEN reinstall
3) download #3 (2nd re-install): fixed the NFMwps problem, but Norton Security threw up all sorts of "fix now" messages that failed because (after 300+MB) the download still wasn't done!
4) online support: no offline downloader available; latest update is 100+MB
5) uninstall and download #4 (3rd re-install): everything works - Live Update was between 350-400MB! and this is immediately after a fresh install that was <100MB! WTF?!
Obviously Norton developers don't have to pay for metered internet connections! Newsflash Norton / Symantec - not everyone has a fat pipe with unlimited download quotas!
Please fix this:
1) You've improved the Live Update to death - there is now no way of telling how big the download is, or how far it has progressed - just a big fat blue bar saying "downloading"
2) Allow users (you know - the people who buy your products that pay for your wages) to cancel (or pause) the download gracefully, and your software pick it up where it left off.
3) Allow scans irrespective of how long its been since a "Live Update" - because that's better than your product effectively dying with a leg in the air.
4) Release an offline downloader .dmg! This strategy has helped people who have to "sip the internet through a straw" for years.
