Both Norton and Bitdefender work with all the major operating systems including Windows, MacOS, iOS, and Android devices.

Effectiveness against malware

When deciding which antivirus product is best, it’s important to know which one will do the best job at protecting your PC against malware. I ran some tests to see how each product performed.

The first test I performed checked for malware threats in real-time, instead of waiting until a scheduled scan time to check my PC files. I also ran a second malware test where I downloaded sample malware files from The European Institute for Computer Antivirus Research (EICAR). I turned off real-time detection and ran a full system scan and a quick scan to see how well the malware was detected and quarantined.

To add to my own tests, I checked out some of the most recent antivirus tests managed by the major independent antivirus test labs. Take a look at the table below comparing the test results from both Norton and Bitdefender. These tests were performed on my PC with three different lives samples and four EICAR samples:

Test FileEICAR Sample 1EICAR Sample 2EICAR Sample 3EICAR Sample 4Live Sample 1 (Adware)Live Sample 2 (Trojan)Live Sample 3
(Trojan)
NortonBlockedAllowedAllowedAllowedBlockedBlockedBlocked
BitdefenderBlockedBlockedBlockedBlockedBlockedBlockedBlocked

The results showed Norton blocked just one of the EICAR samples but allowed three, compared to Bitdefender which blocked all four of the EICAR samples. Norton blocked the .txt file and the download from EICAR.com on HTTP but allowed zip files. On HTTPS, the .zip files and the .txt files were allowed while the Eicar.com file was blocked.

Both Norton and Bitdefender immediately detected and deleted all three live samples.

To add more depth to the analysis, I looked up the latest test results from AV-Test and AV-Comparatives, two of the best-known independent AV testing labs.

During March and April 2020 Bitdefender scored 100% in their protection rates against malware attacks, inclusive of web and email threats (real-world testing). Norton also scored 100% in March, however, in April it scored just shy of 100%, at 99.5%.

I also looked at AV-Comparatives latest Malware Protection test from September 2019. Bitdefender scored 99.5% and Norton scored 99.9% online protection rate, putting Norton just slightly higher than Bitdefender.

AV Comparatives also has another useful tool in testing the best antivirus programs: a false alarm test. This test is useful in seeing how accurately a file or app is identified as safe or as a threat. The lower the number of false alarms the better. False positives occur when the antivirus flags a non-malware file as malware and can therefore be an annoyance.

The test results from September 2019 show seven false alarms for both Norton and Bitdefender, meaning they are on an equal playing field in terms of false positives.

Impact on PC Performance

The impact antivirus programs have on your PC performance is an important thing to consider and is something to be aware of when deciding which one is right for you. To find out which of the two antivirus programs had the best performance numbers, I captured data while running both full and quick scans. To verify my findings, I looked at the performance scores for both Bitdefender and Norton from some recent independent tests.

The table below shows the results of my test and how long it took to complete, plus the number of items that were scanned. The time it takes to complete an antivirus scan is affected by a number of factors such as the speed of the PC, the number of files that need to be scanned, and the antivirus program that you are using.

Test TypeFull Scan Time (minutes)Full Scan Iterms ScannedQuick Scan CPU Utilization %Quick Scan Memory Utilization %Quick Scan Disk Utilization %Quick Scan Time (seconds)
Norton121970000377641171
Bitdefender110420000056813577338

A full scan with Bitdefender completed in 110 minutes and scanned 4.2 million items, compared to Norton which took 121 minutes and scanned 970,000 items.

Next, I tried running a quick scan with each antivirus. Norton completed the scan in 171 seconds, while Bitdefender completed the quick scan in 338 seconds.

I also recorded some data to see how my PC’s resources were affected by both antivirus programs.

Test TypeControl CPU Utilization % (no scan)Control Memory Utilization % (no scan)Control Disk Utilization (MB/s) (no scan)Full Scan CPU Utilization %Full Scan Memory Utilization %Full Scan Disk Utilization (MB/s)
Norton1472138475381
Bitdefender32746556813577

Bitdefender recorded a higher CPU Utilization than Norton when running both programs. Bitdefender also recorded a higher control disk utilization when not performing a scan. During a full scan, Bitdefender used less CPU than Norton. The biggest difference is in the full scan disk utilization: Bitdefender utilized 3,577 MB/s and Norton came in at 381 MB/s.

Next, I analyzed the results from some other independent tests. The tests run by independent labs show how each antivirus impacts PC performance during eight common tasks:

  • Downloading files
  • Browsing Websites
  • File Copying: First and subsequent run
  • Installing/uninstalling applications
  • Archiving / unarchiving
  • Launching applications: First and subsequent run

Each task is given a rating ranging between very fast and slow.

In the AV-Comparatives Performance Test from October 2019, Bitdefender scored “very fast” in seven out of eight tests. Norton’s fell just shy with six “very fast” results.

Norton beat Bitdefender in File Copying speed. However, Norton was slower when archiving/unarchiving, installing and uninstalling applications and launching applications on its first run.

When it comes to performance, Bitdefender performs slightly better, although not by much. There was only a minor impact on speed and performance while I ran a number of tasks on my PC, which the other independent tests verify.

Sign Up and Installation

Signing up is simple for both Norton and Bitdefender.

Norton clearly lays out the price, discount, and the renewal price after the first year. There is also an option to add the Norton Computer Tune-Up, which gives access to Norton-certified technicians who will help make your PC or Mac run better.

Bitdefender also displays the price and discount clearly. However, by default, it enrolls you in an automatic renewal after the first year. If you do not want to renew, make sure you tick the opt-out option, otherwise you may be caught out.

How easy is the interface to use?

Both programs have a very simple interface. Bitdefender is clean and simple, using a black and neon green color template. When opened, Bitdefender’s dashboard proclaims, “You are safe,” making it quick and easy to see if everything is working. It has the usual list of your devices alongside protection, privacy, and utilities sections. There’s also a section for you to share your suggestions and things you would like to see in any future updates.

Norton’s signature grey, black and yellow color scheme is laid out to ensure ease of use. The dashboard, like Bitdefender, lets you know if you are protected. From the dashboard you will be able to access security, identity, performance, and other sections. Norton 360 Deluxe also includes a web portal where you can manage protection for up to five devices.

Customer Support

Norton 360 Deluxe

Norton offers 24/7/365 support on all of its product tiers. There is an online community forum, FAQ, and live chat support. Support is available through its Facebook and Twitter channels. However, unlike Bitdefender’s free phone support, Norton’s phone support costs extra.

Bitdefender Premium Security

Bitdefender Premium Security boasts an extensive support hub, with many common problems answered on their website or demonstrated through online videos, which is great if you want an easy fix. If this is not doable, you can contact support via email, phone, online chat, or through their expert community forums.

Conclusion

Both programs are well-suited for looking after your devices with high malware detection rates. Norton scored slightly higher in independent tests, while Bitdefender blocked more of the samples used in my own testing.

Norton and Bitdefender add some great features on top of the antivirus engine, and in all honesty, it really depends on what you need most that will determine which is best for you.

Due to its better performance in independent tests, lighter system impact, and lower price point, I am going to award the narrowest of victories to Norton over Bitdefender. However, while Norton 360 is affordable and provides everything most people are looking for, if you are looking at securing more than five devices, then Bitdefender is an excellent option for you.
