1. Virus Scanner — Bitdefender Is Much More Efficient at Detecting and Removing Malware Through Scans
Bitdefender is among the best antiviruses at successfully detecting and eliminating malware via scans. One of Bitdefender’s standout aspects is that it uses machine learning and its massive virus directory to detect and remove threats from your system effectively.
Bitdefender offers 5 scanning options:
- Quick scan — Scans computer memory, temporary files, and common hard drive areas for threats.
- System scan — Scans your entire system to find malware, viruses, and other threats.
- Vulnerability scan — Scans your system and network to identify any vulnerabilities that could lead to unauthorized access.
- Rescue environment scan — Reboots your system into a rescue environment to get rid of malware that can’t be eliminated while the operating system is running.
- Custom scan — This lets you specify what you want to scan.
All of Bitdefender’s scans are quite useful, and each one has various use-cases. In all my tests, Bitdefender’s scans successfully detected 100% of the malware on my system and eliminated it with ease.
ESET’s scans are great at removing malware but aren’t on the same level as Bitdefender’s.
ESET comes with the following scans:
- Full system scan — Scans your entire system to remove malware and other threats.
- Custom scan — Let you choose which parts of your system you want to scan.
- Removable media scan — Scans removable devices such as USBs.
It’s worth noting that there’s no quick scan option in ESET, but, as it turns out, it always runs specific scan tasks at startup to make up for this.
During my tests, ESET did not perform as well as Bitdefender. It took a lot longer than Bitdefender to finish its scans, didn’t detect 100% of malware, and also gave more false positives.
Nonetheless, ESET successfully eliminated over 99% of the malware on my system, so it isn’t a bad choice by any means. Both antivirus suites are able to compete favorably with the top antivirus options in the industry in of detection rates.
Bitdefender has perfect detection rates during scans, so it’s clear that it’s the winner here.
Virus Scanner Winner: Bitdefender

2. Real-Time Malware Protection — Both Antiviruses Provide Flawless Real-Time Protection
Both Bitdefender and ESET are excellent at real-time protection and offer flawless protection against 0-day threats. I tested their real-time protection in various ways, and they successfully blocked every single threat without fail. Also, neither antivirus gave any false positives.
Bitdefender and ESET successfully spotted and got rid of malware in real-time before it could infect my system. Both antiviruses have a 100% detection rate against the latest threats, so you should have peace of mind when using either one.
ESET has various great web protection tools like anti-spyware and anti-phishing that help add additional layers of security. Bitdefender also offers a TrafficLight extension that successfully filters malicious web pages and prevents phishing attempts.
Since both antiviruses provide effective real-time protection, I’m calling it a tie in this category.
Real-Time Malware Protection Winner: Tie

3. System Performance — ESET Has a Smaller Impact on System Performance
While neither antivirus has a massive impact on system performance, I found that ESET uses system resources a lot more efficiently. I tested both antiviruses’ impact on my test system during scans and while idle to see which one slows it down more, and ESET came out ahead.
In my tests, I learned that Bitdefender consumes more system resources, especially during scans. My U usage often went past 50% while I was running scans with Bitdefender, and it also had high disk and memory utilization.
ESET, on the other hand, is much lighter during scans. Even running full system scans, my U usage never sured 50% with ESET.
Something interesting is that ESET consumes more resources than Bitdefender does while idle. This isn’t a major problem, though, because neither antivirus is demanding enough while idling to affect your PC’s performance significantly.
All things considered, ESET is the better choice whenever system performance is a priority.
System Performance Winner: ESET

4. VPN — Bitdefender Is the Only Choice Between the Two With a VPN
It’s clear already that Bitdefender wins in the VPN category because ESET doesn’t offer a VPN of its own. I tried out Bitdefender’s VPN, and, while it wasn’t on the same level as
Browsing the web using Bitdefender’s VPN feels very smooth because there aren’t any unnecessary slowdowns. I was also pleased with its streaming capabilities because it lets me easily access my home streaming services and enjoy my favorite shows in HD.
Bitdefender’s VPN uses AES 256-bit encryption to secure your online activity while using it. Unfortunately, the bandwidth is limited because it only offers 200MB daily. However, since ESET doesn’t even have a VPN, Bitdefender comes out on top.
VPN Winner: Bitdefender

5. s — Bitdefender Offers a Thorough and Useful Suite of s
While both antiviruses offer s, Bitdefender’s are a lot more thorough than ESET’s. Both suites are easy to use and don’t take more than a few minutes to set up, though.
Bitdefender’s s offer a lot of tools to help control and monitor your children’s activity. You can easily block access to certain apps and websites and will be notified if anyone tries to access them. Plus, there’s location tracking to help you keep track of where your children are at all times. You can also use Bitdefender’s s to track how much time your kids spend online.
On the other hand, ESET’s s aren’t nearly as feature-rich. The most you can do with ESET’s controls is block access to specific websites and apps, or you can specify entire website categories to block. Unfortunately, you cannot do much else using the s in ESET.
Overall, thanks to its more in-depth s, I consider Bitdefender the winner here.
s Winner: Bitdefender

6. Firewall — Bitdefender’s Firewall is Superior Because It’s Much More Intuitive
I was happy to learn that both Bitdefender and ESET offer a secure firewall. However, while both firewalls are great at keeping you safe online,
The firewall, like the rest of Bitdefender’s app, has a clean and intuitive design. It’s easy to view all its rules, add new ones, or reset current ones. Plus, you can specify which apps you don’t want to be affected by the firewall with just a few simple clicks. Bitdefender’s firewall also lets you select different behaviors for home, work, and public networks. ESET’s firewall is just as secure but simply doesn’t feel intuitive to use. I found it really hard to configure ESET’s firewalls to my liking. It does have different filtering modes to determine how strict the firewall is, but it’s unnecessarily hard to configure on your own. So, even though both firewalls are very secure, Bitdefender is the winner because of how intuitive its firewall is. Firewall Winner: Bitdefender Try Bitdefender risk-free for 30 days! You’ll be pleased to know that there’s a manager built into both ESET and Bitdefender. Both managers are capable, but I found that ESET’s feels much better to use overall. ESET’s manager comes with a straightforward and intuitive design that makes it easy to figure out. You can easily use this manager to save sensitive information like s, card details, identities, etc. There’s also a generator that you can use to generate up to 32-character-long s with numbers, lowercase letters, uppercase letters, and special characters. Plus, it uses AES 256-bit encryption to safeguard your sensitive data. Bitdefender comes with a very capable built-in manager as well.It uses AES 256-bit encryption to keep your information safe and can be used to store s, banking details, identities, and more. Bitdefender’s manager feels solid, but I found ESET’s more intuitive. Overall, while I was impressed with both managers, but I consider ESET the winner because of its ease of use. Manager Winner: ESET Try ESET risk-free for 30 days! ESET and Bitdefender offer tools to improve gaming system performance. Still, I found that Bitdefender is a lot more effective at this. To set up the Game Profile, you can head into the Profiles section in Bitdefender’s utility menu. The Game Profile will automatically detect your games, but you can add them manually in case it doesn’t.
ESET offers Gamer mode but for some reason, it is located in its ‘Computer Protection’ section. The Gamer mode doesn’t need to be set up and is a simple toggle. Unfortunately, ESET’s Gamer mode fails to deliver noteworthy performance improvements while gaming. It only silences notifications, which Bitdefender’s game profile does as well. It’s clear that Bitdefender is the winner of this category. Bitdefender’s Game Profile offers a noticeable performance boost, while ESET’s Gamer mode only silences notifications. Gaming Mode Winner: Bitdefender Try Bitdefender risk-free for 30 days! Bitdefender wins in this category because ESET doesn’t have any optimization tools worth noting. Bitdefender doesn’t have a large variety, but it does have the OneClick Optimizer, which I found useful. Bitdefender’s OneClick Optimizer scans your system for junk files, registry issues, cookies, and similar things and cleans them up to free up space. I successfully cleaned up over 1GB of space with just one click. On the other hand, ESET doesn’t have any useful optimization tools. The only thing that comes close is its system cleaner, but it doesn’t do much to optimize your system.
Bitdefender is the winner as far as optimization is concerned because ESET doesn’t offer anything that can compete in this category. Optimization Tools Winner: Bitdefender Try Bitdefender risk-free for 30 days! I was far more impressed with Bitdefender when it comes to -friendliness than I was with ESET. For starters, the installation process for both ESET and Bitdefender is very straightforward. You can easily the setup, run it on your system, and follow the steps to have it up and running within minutes. However, while installing both antiviruses is quite easy, I found Bitdefender much simpler to use. It has a more modern and intuitive interface with menus that are easy to browse. Plus, all important features are displayed neatly in most menus, so it doesn’t take more than a few seconds to find something. In contrast, I struggled a bit when trying to make the most of ESET. It has a fairly dated interface that hasn’t evolved much over the years. So, it can sometimes be a bit hard to navigate through the menus and use a specific feature. Even during my tests, I had problems finding the Gamer mode because it was in the Computer Protection menu for some reason. Overall, Bitdefender is much easier to use than ESET. Both antiviruses are easy to install, but Bitdefender has a more intuitive interface that’s easy to navigate. Other Features Winner: Bitdefender Try Bitdefender risk-free for 30 days! Bitdefender is a much better choice than ESET if you want a feature-rich antivirus. Although both offer solid protection against threats, Bitdefender offers a wider variety of features. Bitdefender has various features, including a reliable VPN, a secure file shredder, and a safe online banking environment.. Plus, it offers anti-tracking to block web trackers from collecting identifying data about you. All of its additional features, alongside the excellent threat protection, provide fantastic value for your money. ESET also has its share of features like webcam protection, a network security monitor, and anti-theft. However, it simply falls short compared to Bitdefender. Bitdefender is the better choice if you want an antivirus that combines security with various useful features. Device Compatibility Winner: Bitdefender Try Bitdefender risk-free for 30 days!

Whenever I needed help with any issue with either antivirus, I found it quick and easy to get the help I required.

You might often find that someone has had the same issue before, and an expert has already posted a solution. However, if not, you can still ask for yourself, and an expert will quickly get back to you. Alongside everything else, ESET and Bitdefender offer a helpful online knowledge base with lots of helpful information. You can consult this knowledge base for most common issues and will usually find the solution you need with ease. Overall, both antiviruses offer impressive customer , but Bitdefender is the winner because its live chat is available throughout the day. ESET does offer live chat, but it’s only available during specific windows of the day, so it isn’t as reliable. Customer Service Winner: Bitdefender Try Bitdefender risk-free for 30 days!

Plus, Bitdefender has an app for iOS while ESET doesn’t. Also, I noticed that Bitdefender’s plans include for multiple devices, while you need to pay extra to use ESET on more than one device.

Furthermore, I was exceptionally satisfied with the straightforward process of utilizing the money-back guarantee to obtain refunds for both antivirus programs. With the intention of ing the reliability of their money-back guarantees, I proceeded to request a refund for each antivirus. I ed Bitdefender to ask for a refund and received it in a few days, with no questions asked.

It’s a tie here because both antiviruses offer a money-back guarantee and fully deliver on it. Money-Back Guarantee Winner: Tie Try Bitdefender risk-free for 30 days!

Plus, all its plans offer much better value for money than ESET’s. Both Bitdefender and ESET excel at safeguarding your system from threats in real-time and through their scans.
