Norton is a brand with a long history and a strong reputation on the security market. We wanted to see what their latest security suite looks like, and to check how efficient it is in protecting its users from modern day cyber threats. Over the last few days, we used and tested Norton Security Premium, and now we would like to share with you everything we liked and did not like about it. If you want to have a better idea and a clearer understanding of just how good Norton Security Premium is and whether it is worth buying as your main antivirus, read this review:
What is Norton Security Premium good at?
Norton Security Premium is a security software that is good when it comes to:- Offering top-notch protection against all kinds of malware
- Giving you a firewall module that can protect you against network attacks and other threats, especially when you connect to public networks
- Providing you with a user interface with good design, which is easy to use even on touchscreens
Norton Security Premium vs. Norton Security Deluxe
The average difference in price between Norton Security Deluxe and Norton Security Premium is about 20 percent. Although the security you get from both these products is equally good, the bundled tools differ. Compared to the Deluxe version, Norton Security Premium includes Backup and restore and 25 GB of online storage space, was well as parental controls. Also, Norton Security Premium can be installed and used on up to 10 different devices, while the Deluxe version can be installed only on 5 devices at one time. You can find more details here: Norton Security Editions. Considering all of the above, our opinion is that Norton Security Premium is the better deal, if you have a large number of devices that need to be secured, or you are a parent. For everyone else, Norton Security Deluxe works just fine.Pros and cons
These are the essential strengths of Norton Security Premium:- The antivirus engine is fast and efficient when removing malicious code from your Windows computers and devices
- Norton has a minimal negative effect on the performance of your Windows devices
- The user interface is nicely designed, and it is easy to understand and use, even on devices with touch
- The firewall module does a good job when you connect to public networks
- The parental controls tool is easy to use and works very well
- If you are not using Google Chrome or Mozilla Firefox, you are virtually on your own while browsing the web. Norton does nothing to protect you when using other web browsers
- Norton tries to change your browser's homepage and default search engine to web sites maintained by Norton and Ask.com (a website with a bad history)
- It does not bundle a VPN tool to protect users when connecting to public WiFi
Verdict
Norton Security Premium is a solid product that is more than capable of protecting you against viruses and network threats. We liked the user interface, the way it looks and how easy it is to understand and use. However, this product has an important downside which lowers its effectiveness: it offers protection only in a limited number of web browsers (Chrome and Firefox), and only if you install its browser extensions. Also, we do not like the fact that Norton Security Premium tried to change the homepage of our web browsers and the default search engine. This is a bad tactic usually employed by free software, not by premium security suites that cost money. All in all, if you look at its price and take everything else into account, Norton Security Premium is a good security suite, with the condition that you stick to Chrome or Firefox as your default web browser. People using other web browsers should stay away from it.The download and installation experience
To get Norton Security Premium on your Windows computer, you have to start by downloading it from Norton's website. You get to download a small executable file called NSPremiumDownloader.exe, with a size of just 1.06 MB. The install wizard downloads 200.60 MB of files needed to install the security suite on your computer. Once the download is done, you can choose whether you want to join Norton Community Watch, so that the security suite can automatically send security threat information back to Symantec. This is something we recommend that you enable, because it helps Norton react faster and better to cyber threats. If you want to, you can change the default installation folder, but that is all you can customize about the installation. Then the installation takes its course and should be done in a minute or two. Once that is also done, you must activate the trial version of Norton Security Premium, and for that, you have to either sign in using your Norton account or create an account. To create it, you have to provide an email address, a password, a name, a phone number, and the country you live in. We do not like the fact that Norton insists on collecting personal information from users, even if all they want to do is evaluate their product. Once activated, the installation is done, and the user interface is loaded. It looks elegant and simple, but it also comes with a surprise: the virus definitions database is two months old. We waited for about 15 minutes, but the security suite did not trigger an automatic update of its definitions database, so we started a manual update. That meant that we had to download another 259.39 MB of files from Norton's servers. Downloading Norton Security Premium is simple, and installing the security suite is easy. However, there is quite a lot of data that needs to be downloaded from Norton's servers and the suite does not update itself as soon as you install it. You must trigger a manual update to get the latest protection as soon as possible.Integration with Windows, web browsers and universal Windows platform apps
Norton Security Premium is a security product that is well integrated with Windows 10 and its features. For starters, it automatically disables Windows Firewall and Windows Defender during its installation. This is a positive because it eliminates possible conflicts and performance issues that can arise when running two similar security products at the same time. Norton is also working well when it comes to the networking features offered by Windows. We could create and join a homegroup without any problems, we could share files over the local network, and we were able to download, install and use universal Windows platform apps without being negatively affected by Norton Security Premium. We appreciated that Norton can automatically detect the profile you set in Windows for the network connections that you are using and adjust its firewall protection accordingly. Regarding web protection, Norton Security Premium checks the websites that you visit and protects you against dangerous ones, but only with two conditions. The first is that you use Google Chrome or Mozilla Firefox as your web browser. The second condition is that you have to install the Norton Safe Web extension in Firefox or the Norton Security Toolbar in Chrome. If you use any of these two browsers, when you open them the first time after you installed Norton Security Premium, you are invited to "Enable All Norton Extensions." The extensions available are Norton Safe Search, Norton Home Page, Norton Safe Web (in Firefox) or Norton Security Toolbar (in Chrome), and Norton Identity Safe. You can click or tap the Enable links to download and install the extensions. We strongly recommend that you do that for Norton Safe Web in Firefox and Norton Security Toolbar in Chrome. Otherwise, you are left unprotected against malicious websites, such as phishing web pages. If you need a password manager, you could also install the Norton Identity Safe. However, the Norton Safe Search and Norton Home Page are things we recommend that you avoid installing. They are only changing your browser's homepage and the default search engine to Norton websites that are powered by Ask, a web service with a bad reputation. Norton Security Premium seems to be a lightweight product. On our test laptop, it consumed only 55 MB of RAM in normal usage situations. Another positive is that all its processes are protected against unwanted termination, so nasty viruses cannot easily disable this security suite. If the boot speed is your concern, you should know that Norton Security Premium does not increase the boot time of your Windows device. We used BootRacer to measure the boot times of our test laptop, and the results we got were the same before and after installing the security suite. To check whether the internet or local network speeds are affected by Norton Security Premium, we also ran a few tests with Speedtest.net and with LAN Speed Test. All the tests that we ran showed that the download and the upload speeds were not negatively affected by this security suite. Norton Security Premium is a security product that integrates well with Windows 10. We like the fact that it does not seem to have any negative effect on our computer's performance or on network/internet speeds. However, we do not like that it only protects you when browsing the web with Chrome or Firefox. Other browsers are not protected. We also do not like the fact that Norton tries to make its users switch their browser homepage and default search engine.Ease of use & configuration
The user interface offered by Norton Security Premium has a good design: nice colors, good structure and lots of switches and large buttons. It is easy to use on touch screens too. The main console is split into two large sections. The one below is made of large tiles that give you access to the most important sections/features of the security suite, while the top of the window shows a few details related to the section you selected on the bottom. The default section is Security, and it shows you whether "You Are Protected" or not. If you dive into the settings offered by Norton for a certain section, you can see the switches we mentioned above. They are easy to use, including for beginners. The available settings use a common language that any user, experienced or beginner, can understand. However, if you cannot grasp what some settings do, look for the small question mark usually found on their right side. Clicking or tapping on it opens your web browser and gives you all the information you need. Also, if you need further help or support, there is also a Help Center that you can access anytime you want. If you want to talk to a real person, you can connect to the community forums; you can live chat, ask for help on Facebook or Twitter, or even call Norton's support technicians on the phone. If you like statistics and reports, you should know that Norton Security Premium provides logs that are both detailed and easy to understand. Plus, you also get a nice looking 30-day report of what Norton did to protect you. Norton Security Premium lets you know when something important is taking place on your computer. We have seen alerts from the antivirus engine, but also notifications from the firewall. Norton Security Premium is a security product that looks good and is also easy to use and understand. We especially appreciate the way its user interface is structured and the fact that it is easy to use on touchscreens too. On the next page of this review, you can see how capable Norton Security Premium is at protecting your Windows computer from network attacks and malware. You can also see what additional features are included in this security suite, and check our recommendations for what settings you should adjust.Firewall protection
Regarding firewall protection, we like that Norton Security Premium can detect the network profile you set in Windows and adapt its protection accordingly. When you set your network as private or public, so does Norton's firewall module. This is a good approach, and we wish that many other security products did the same. To get an idea of how efficient Norton Security Premium is regarding firewall protection, we used two network vulnerabilities scanners: Nmap and Nessus. When we used a private network profile, Nmap found 8 open ports and Nessus found 6. When we set our test laptop to use a public network profile, neither Nmap nor Nessus managed to identify any open ports or other significant information, except for the MAC address, but that is not important from a security point of view. Norton Security Premium offers a solid firewall that can protect you efficiently, without needing any special input from the user. It is especially effective when you are connected to public networks, which is great.Antivirus and antispyware protection
We began by checking how good Norton Security Premium is at protecting you while surfing the internet in your favorite web browser. To do that, Norton Security Premium installs a security toolbar in Chrome and a security extension in Firefox. Both of them check whether the websites you intend to visit are safe or not. Unfortunately, Norton's security extensions are not offered in any other web browsers. We used these browsers and tried to navigate through a series of malicious and phishing websites. Norton promptly stopped us with a danger alert. However, in Microsoft Edge and Opera, we were able to visit all the malicious websites we wanted. Unless you are a Chrome or a Firefox user, you will not get any web protection from Norton Security Premium which is not good. The next thing we did was to check what the security suite did when we connected a USB memory stick filled with malware. The good news is that the Norton Security Premium automatically scanned the memory stick as soon as we plugged it in. It identified and removed 9 out of the 12 infected files on it, and it cleaned the rest of 3 when we opened them in File Explorer. This is an average result. Norton should have cleaned everything from the start. For the next test, we took our Windows 10 laptop, and we infected it with a bunch of nasty viruses and ransomware. Then, we went online and asked Norton Security Premium to download and install itself on our computer. The security suite was able to do that and, as soon as it started its core processes, it began detecting and removing the malicious files we placed on the computer. It took two reboots and a full computer scan, but the laptop was usable again when all was said and done. An antivirus engine is not good enough if it is too slow, so that is why we also measure the time it needs to run a full antivirus scan of our 126 GB system partition with 35GB of data on it. To scan it, Norton Security Premium required only 2 minutes, which is very fast. Finally, we also took a look at what independent security organizations had to say about Norton:- AV-Test rated Norton with a verdict of 6 points out of 6 for Protection, 5.5 points out of 6 for Performance and 6 points out of 6 for Usability.
- AV-Comparatives gave Norton their top Advanced+ mark for the Performance and Real-World Protection tests, and their basic Tested mark in the Malware Protection test.
- Virus Bulletin did not test Norton's security products, and the company is not a part of their tests for a long time.
Extra features
Besides its main protection features, Norton Security Premium also bundles a few additional tools that you may find useful:- Norton Identity - a password manager that stores your passwords safely and keeps them synced between different computers, browsers, and mobile devices. It works with Microsoft Edge, Mozilla Firefox, Google Chrome, Safari, and Android and iOS.
- Norton Backup - is a backup and restore tool that lets you create copies of your data. You can save those backups locally, on your computer, or you can upload them to Norton's cloud space, where you get 25GB of free space included.
- Norton Performance - includes a few tools used for optimizing your computer's performance. You get an Optimize Disk tool, a File Cleanup tool, and a Startup Manager. They do what they say, but we do not find them too useful considering that what they do can also be done from Windows 10.
- Norton Family - is a product that is not bundled with Norton Security Premium. To be able to use it, you have to download and install Norton Family separately. We found it to be easy to configure and use. If you have children, it can be useful to you.
- Norton Studio - is a universal Windows app that lets you view, manage and explore the Norton products that you own. It can be useful to some users.
Default settings you might want to adjust
Norton Security Premium is a security suite that is well configured in general, but there still are a few settings that you might want to change:- If you do not want to get any "Special Offer Notifications" from Norton Security Premium, you should disable this setting. You will find it in "Settings -> Administrative Settings."
- If you want to stop notifications and background tasks so that you are not bothered with information about what is happening on your computer, you can enable the Silent Mode. You can find this option in "Settings -> Administrative Settings."

Have been running Norton 360 on my XP (svc pack 3) machine without problems. Because Norton sales rep explained 360 was being phased out and Security Premium was totally compatible and included better features, I opted to renew with Security Premium. BIG MISTAKE!!!
After installing excel did not function properly, email messages would not open properly, email links would not open, internet windows kept crashing – totally locking up computer, unit would not respond to close & restart commands, had to unplug to reboot. Upon restarting, some desk top icon positions were rearranged. Just spent an entire day screwing with tech support trying to repair. Very courteous, but obviously not prepared to deal successfully with the problem. After much wasted time & ineffective communication, they removed & reinstalled program. Half hour later same problems. So, I have wasted 8 hrs of my life – and now will need more – dealing with a product that obviously is NOT compatible with XP – the techs response was to only open & use one internet tab at a time. Yes – that will be great for business productivity! There is ample memory free on this device.
As far as I am concerned, Norton Security Premium is NOT COMPATIBLE with XP.
You should stop using Windows XP. It is no longer supported by anyone and you open yourself to many security issues.
I am glad I read your article. I was going crazy trying to put the Norton Vault on the google chrome. I don’t sign up with Google because they are invasive, however, IE is not great for searching. I keep IE for my basics – I don’t know about the other security software which may be good for my HP running Win 7 64 bit. I’m waiting for my present equipment to die before I go for something else. I now have some idea about renewing Norton. Thanks!

Codrut Neagu is right. Now you may not have to log onto Norton if you are using the Windows 8 Operating System but you DO have to logon using Windows 7, otherwise Live Update will not download updates.
This is what I would like to add to your test
1. Bitdefender, Kaspersky, ESET, GData (just to name a few) all “force” you to give them your email address when using their trial-version.
2. Kaspersky, ESET, FSecure also take their time with downloading updates. Funnily enough, Kaspersky always warned me to update the database when I was offline, but took up to 30 minutes to install updates when I went online.
3. I’m not sure what you mean by browser add-on. You don’t need to switch on the Norton toolbar for browser protection. All antivirus only guarantee full compability with IE, FF, and Chrome. Some support Opera.
4. I suppose resource drainage really varies with the setup you use. I found Kaspersky and Bitdefender slowed down my system a lot while ESET and Norton were really lightweight and unobtrusive
5. Offline documentation for Norton is in the automatically installed pdf handbook.
6. I don’t know what went wrong with your usb-stick testing. The minute I add an external drive Norton scans it. You have to set it up to do that though. However, you have to set it up with the other AVsuites as well.
7. ESET installs without any complaints in an infected OS.
8. Norton 2015 is tested by AV and Dennis Technology Labs. As for why Norton isn‘t tested by AV Comparatives anymore: “…Similarly, testing security products with just a file scan, as seen in the recent AV-Comparatives report and similar types of tests, is misleading. Such a testing approach does not accurately represent the real-world threat conditions seen today – and also does not accurately represent the level of protection provided by a security product. Putting forward conclusions from such flawed testing creates confusion and does a disservice to consumers. Symantec has long been an advocate of independent “whole product” or “real-world” tests that most closely represent the threat environment and utilize all of the proactive technologies provided with a product. Symantec consistently ranks at the top of real-world tests performed by independent testers. The Norton products have received recognition for industry-leading protection in real-world, unsponsored tests conducted by independent testing labs such as AV-TEST and Dennis Technology .These labs evaluate each product in realistic infection scenarios that typical users might experience.” By Alejandro Borgia, senior director, product management, Symantec Corporation
I find it working pretty good so far better than some others i’ve tried which is in all 8 av’s.
First of all, mind your language.
Secondly:
1. There are security vendors that don’t force you to register just to use trials of their suites. That is very nice! Forcing you to give your personal details is NOT OK. What if you don’t like the suite and you won’t buy it? Why should you create an account you’ll never use?
2. The best security suites on the market don’t let you download malware on your computer. You’re blocked BEFORE it arrives on your computer. You don’t need a neural implant for that.
3. Scanning a USB memory stick before actually accessing it is a good approach. Scanning things only when you access them is a lesser approach. Say you plug in a stick and you only access one folder out of many on it. That folder is cleaned, the others are not. Than, you give that stick to a friend who doesn’t use an antivirus. Are there any chances for him to he get infected?
4. You say I’m not in my right mind if I want to test how a security suite handles an already infected computer. Just look around… many users buy an antivirus especially AFTER their computers are infected. Why? To clean the malware already found on their drives.
Thirdly, we don’t “benchmark” products, we’re testing them in real life scenarios.
Oh, one more thing.
You were clearly ‘unable’ to infect your machines with Norton 2015 installed. You leave this tidbit out. Instead, you PRE-INFECT a machine in attempts to bypass THE WHOLE PURPOSE OF THE PRODUCT so you can then bag on it? Incredible…
If this site pays you, they need to stop…
Oh look, a random **** reviewed it, without actually having much technical knowledge to be a technical reviewer. Not sure why I am responding, as this review is pure ****.
Add the fact that you absolutely have to create a Norton account and you will understand why our bad feeling about this suite.
Interesting.. He had a ‘bad feeling’ before even testing it? Then he says the fact you need to register is ‘ridiculous’? A lot of security products require you to register, what’s the big deal?
Norton Security 2015 only acts when you start downloading malware on your computer.
As opposed to what? Using some neural net implant, to determine malware BEFORE it arrives? This isn’t a UTM, it’s an ENDPOINT product. Maybe someone should point out to this guy the difference between a UTM/NGFW, URL Scanner, and Anti-Malware product? The fact is, Norton ‘sandboxes’ the download, then runs a serious of diagnostics, it’s not actually ‘downloaded’ in the real sense that you can run it and infect yourself, it’s still isolated, and being evaluted.
It only scans the drive when you access it, and only the folders you open (not the entire drive). The worst part is that it only detected half of the 26 infected files we had on the memory stick. We triggered a manual scan for this drive. This time, Norton Security 2015 managed to find 2 more malware samples.
Aren’t things SUPPOSED to be scanned as they are accessed? Does everyone really want incessant ‘Do you want to scan this USB?’ or long scans everytime a drive is placed in? I sure don’t, and I am sure most people would rather not endure that annoyance. So let’s scan when it’s accessed. So it detected 15 out of 26 samples on the drive. Do you run any of the undetected ones? No – you didn’t.. I challenge you to run each and every one of them, one at a time, and let us know how it went. We know how it will go – Norton will implement ‘additional’ technologies (Insight, Sonar, Reputation), and stop every one of them. Since they aren’t ‘running’ they aren’t really a threat – but Norton decided to take care of more than half anyway – be thankful.
Then, we took a clean Windows 8.1 installation and infected it with a dozen malware samples. Then we downloaded and installed Norton Security 2015. Everything worked smoothly. Once installed, the suite should have automatically launched its protection processes. But it did not!
So you essentially ran a test that nobody in their right mind would consider a valid test.. Taking a clean machine, horrendously infecting it, then taking a PROTECTION suite, and expecting it to install, and clean the machine? Let’s not even mention the fact that you loaded it up with trojans that likely WILL prevent ‘known’ products like Norton (and every other one) from being installed. That’s why MBAM has Chameleon developed – specially for this. It’s at this point I want to call you a m***, but I will refrain.
