In the new version, I like that the installation starts in one click, as well as its completion. I now have the ability to view and save logs that allow me to contact technical support.

It's a really bad idea to list the virus definition updates as software listing on macupdate. can a moderator fix that please?

INSTALL AT YOUR OWN RISK. Norton of any flavor risks loss of your data. It installs crap all over your computer with innocuous names that defy search and removal. Like bamboo – it also multiplies and expands. Even if you remove it – one missed tidbit can replicate the whole app again. THIS SHOULD BE CLASSED AS A VIRUS.
