All of the features are available from a single icon at the top of the screen. Click it and a drop-down list appears; you can then choose the security feature you want to customize or run. The anti-virus features lets you select individual folders of files to scan, do a quick scan of all your files, or do a more comprehensive system scan. You can set the scan to ignore certain files and folders. The firewall also allows for a good deal of customization.
Generally, though, Norton Internet Security for the Mac is a set-and-forget piece of software. Install it, use the defaults, and you'll be protected.
Norton One's Android security software, Norton Mobile Security, protects Android devices against a wide variety of threats. You can scan for malware manually or on a daily, weekly or monthly schedule. You can also scan your SD card, which is vital for Android users who have moved apps to their SD cards.

The anti-theft feature is especially well done. You create a password, and if you lose your phone or it's stolen, you can send a text message to it from any phone with the word "lock" followed by your password. That will lock the phone, and it can only be unlocked when your password is entered.
If you download a free add-on, you can also locate your device by going to the Norton Anti-Theft website; from there, you can remotely trigger your device's camera to take a photo, which may help you in finding the device or identifying a thief.
However, you can't lock your device remotely from the Web -- only from another phone -- so your only choice for remote lock is sending text message, which is far from ideal. This is something that should be fixed.
There is a robust set of tools for blocking spam phone calls and text messages. You can enter the numbers you want to block by typing them in manually, selecting them from your contacts or selecting them from your call log or SMS log.
When someone from your blocked list calls you, the call is sent directly to your voicemail, so you aren't bothered by it. When someone from the blocked list sends a text, it simply doesn't get to you. You can review logs of all blocked calls and SMS messages. And you can easily unblock calls.
A Web protection feature blocks phishing sites and sites known to harbor malware. You can override the block, although the override lasts for only 30 minutes. The block works only with the built-in Android browser, not with third-party browsers such as Dolphin.
It's hard to argue with an all-in-one suite that offers such a full set of security tools. Both the computer-based protection and mobile-based protection of Norton One are stellar, and pack pretty much every security feature you might ask for. Extra features such as Norton Insight and Startup Manager made Norton One stand out even more.
Norton One falls down where most others in this roundup do -- the Web interface. At this point, the Web interface is little more than an easy way to install software and see which of your devices are protected. If you're looking for a fully featured Web dashboard for helping manage security on all of your devices, Webroot SecureAnywhere Complete is a better bet.
