Remove malware with ESET

1. Virus Scanner — ESET Offers Perfect Malware Detection Rates and Faster Scan Times

ESET beats Microsoft Defender in malware detection rates so it wins this category. During my tests, ESET detected 100% of known and emerging cyber threats, better than Microsoft Defender’s 99.5% detection rates.
When it comes to scanning options, Microsoft Defender offers 1 additional option compared to ESET. However, you may not need many scan options as a full or quick scan is often adequate to get rid of most types of malware threats.

ESET has 3 scan types:

• Full scan — checks your entire hard drive for malware.
• Custom scan — selects specific locations on your system that you want to scan.
• Removable media scan — scans external media like USB sticks.

Microsoft Defender offers 4 types of scans:

• Quick scan — checks critical areas of your system.
• Full Scan — scans your entire computer for malware threats.
• Custom — chooses a specific location and files to scan.
• Microsoft Defender Offline scan — reboots your system and attempts to remove stubborn malware before the OS loads.

As for speeds, I found ESET was faster than Microsoft Defender. In my tests, ESET took 30 minutes to scan my entire system whereas Microsoft Defender took a little over an hour for the same scan. I also discovered that in subsequent scans, ESET targets files that have recently changed. This means following scans will be even faster.

With ESET having faster scan times and perfect detection rates, it wins this round. You can get ESET and protect your computer risk-free using the 30-day money-back guarantee

2. Real-Time Malware Protection — ESET Blocks 100% Of Real-Time and Zero-Day Malware

ESET performs slightly better than Microsoft Defender in detecting zero-day malware threats. During tests, ESET scored 100% in real-time protection, putting it head-to-head with the best antiviruses on the market. However, Microsoft Defender’s real-time protection comes close at a 99% rate.

I conducted additional tests to compare the real-time protection of both antiviruses. During the test, I downloaded malware samples from EICAR while both antivirus programs were running in the background. ESET proved to be effective in blocking all attempted malware downloads, including those in zip files. In contrast, while Microsoft Defender managed to stop most of the malware downloads, it could not detect malware in zip files.

ESET and Microsoft Defender will protect you from phishing threats as well. If you click on a suspicious link, the antiviruses will notify you concerning the dangers of the attempted visit and block access to the site.

Both antiviruses provide decent protection against ransomware threats. Ransomware threats mostly target Windows devices, allowing the attacker to encrypt the victim’s files unless they pay a ransom. Microsoft Defender has a Controlled folder access feature that’ll let you specify certain folders so unauthorized apps can’t make any changes to them. ESET will also protect your PC from ransomware and other forms of malware.

To combat ransomware threats, ESET employs a Host Intrusion Prevention System (HIPS) and its corresponding Ransomware Shield feature. This security system monitors program behavior and any suspicious activity is instantly blocked and terminated. Additionally, HIPS can be customized to specify which files or folders should remain unaltered.

Overall, ESET provides top-tier protection against real-time malware attacks, phishing attempts, and other online threats. However, Microsoft Defender comes close and offers nearly flawless protection.

3. System Performance — Both Antivirus Programs Are Light-Weight

ESET and Microsoft Defender are both lightweight antivirus programs, but ESET consumes fewer system resources overall. To measure the impact on the performance of my system, I recorded my laptop’s CPU, memory, and disk utilization. Then, I compared the values when running a scan and when not.
In my tests, I discovered that ESET caused my CPU utilization to surge from 4% to 29% and my memory utilization to climb from 80% to 84% when performing a full disk scan. However, Microsoft Defender’s full scan caused my CPU utilization to spike from 5% to 100%, but my memory utilization remained stable at 74%.

To evaluate their impact on system performance, I conducted a series of tasks such as launching applications and opening web pages while running both antivirus programs in the background. The table below presents the slowdowns I encountered:

Overall, ESET is a better choice as it utilizes fewer CPU resources during a scan or copying of files. However, both antiviruses won’t cause a significant slowdown to your computer.

4. VPN — ESET and Microsoft Defender Offer No VPN

Both ESET and Microsoft Defender offer no VPN, so there’s no winner in this category. If you want an integrated VPN and antivirus package you can instead use Norton’s Secure VPN. Norton provides robust security features, fast speeds, and access to all major streaming platforms like Netflix, Hulu, Amazon Prime, and BBC iPlayer.

Norton offers monthly and yearly plans that support between 1-10 devices. With a starting price of $$$$€€€€€€€29.997.9324925.0819.9924.9929.9927.7929.9929.9930.47/per month, you get access to many of the VPNs security features, including its military-grade encryption, Wi-Fi security, and servers in 30+ countries.

Browse securely with Norton VPN

5. Parental Controls — Microsoft Defender Offers More Parental Control Features

ESET and Microsoft Defender both offer a basic parental control app that functions more like a content filter. You can use it to block access to specific sites or content that may be harmful to your kids. This includes a mix of violent, pornographic, or drug-related content, and others.

In my tests, ESET blocked every category-wide harmful content across all the devices I set it up on. It also logged all the blocks and the time I tried accessing the restricted website. This is good considering it helps monitor your child’s activities properly, allowing you to know which sites they tried accessing.

Microsoft Defenders also offers a decent parental control feature. However, you can only use it on the Microsoft Edge browser. The app allows you to carry out the following controls:

• Choose what sites your child visits
• Set a time when your kids can use their phones
• Receive weekly reports of your child’s activities
• Monitor the health and safety of all devices registered with your account
• Monitor the games and apps that your kids can buy or download

You can enable parental controls from your Windows’ “Family Options” tab by clicking on the “View Family” settings. However, these controls require a Microsoft account, which could be a limitation if your children utilize different operating systems or web browsers besides Microsoft Edge.

There’s no winner in this round. This is because both ESET and Microsoft Defender’s parental controls are relatively weak and only offer a fraction of what you can get with competitor antivirus programs like Norton.

6. Firewall — ESET Offers Customizable Firewall Options

ESET and Microsoft Defender both provide decent firewall protections, but I found ESET’s firewall to be more customizable and easy to use. It successfully blocks off all unauthorized connections and offers different firewall modes as follows:

• Automatic mode — this mode blocks off most inbound connections whilst allowing most outbound connections.
• Interactive mode — allows you to choose whether to block or permit unrecognized traffic.
• Learning mode — an AI-based system that automatically saves rules on your activities to train the firewall.

While Microsoft Defender’s firewall is relatively straightforward, it has a few limitations when compared to ESET. It is not as user-friendly and lacks advanced reporting capabilities. However, it does offer the ability to create rules for inbound and outbound connections and can be configured on private, public, or domain networks.

While Microsoft Defender’s firewall provides decent protection, it is not as comprehensive as ESET’s firewall and can be more challenging to configure. Therefore, ESET wins this round. Overall, both firewalls protected my device effectively from network attacks.

Block network attacks with ESET firewall

7. Password Manager — ESET Provides a Basic Password Manager

Only ESET comes with a password manager among the two antiviruses. ESET’s password manager protects your passwords with industry-standard AES-256-bit encryption. It offers the following features:

• Password generator
• Secure Notes
• Multi-device syncing
• Auto-fill and Auto-save
• Leaked password checker
• Two-factor authentication

ESET’s password manager is user-friendly. The Android and iOS apps are easy to set up and use, likewise the browser extension for Chrome, Firefox, and Microsoft Edge. On these apps, you can save credentials, generate secure passwords, and autofill them on respective websites or apps. However, ESET lacks features like dark web monitoring, and password sharing.

When it comes to features, ESET’s password manager falls short in comparison to those included in Norton or Bitdefender antivirus programs. However, ESET comes out on top in this category as Microsoft Defender doesn’t have a password manager.

Organize your passwords with ESET

8. Gaming Mode — ESET Has a Basic Gaming Mode Feature

ESET offers a basic Gamer Mode feature. It prevents notifications and halts task scheduler activity (such as scheduling system scans) that would otherwise disrupt gameplay. Theoretically, it should also reduce CPU usage by eliminating unnecessary background tasks. However, during my test while playing Call of Duty: Warzone and Rocket League, I did not observe any improvement in performance.

The Gamer Mode feature on ESET protects your gaming by ensuring it:

• Deactivates and delays heavy tasks like deep scanning
• Prevents interruption by turning off notifications
• Prevents alerts that demand user interaction
• Blocks unnecessary background tasks

Overall, ESET’s Gamer Mode doesn’t do anything out of the ordinary. However, since Microsoft Defender doesn’t have a Gaming Mode feature, ESET wins this round.

Enhance your gaming with ESET

9. Optimization Tools — Both Antiviruses Lack Performance-Enhancing Tools

Both antivirus programs don’t offer performance-optimizing tools. ESET only offers a System Cleaner tool that doesn’t really enhance system performance. Instead, it’s only useful for restoring your system to a prior state, resetting system settings, and modifying appearance.

In comparison, TotalAV provides a wide range of PC optimization tools to help your system run faster. For instance, the Smart scan doesn’t just remove malware, but also junk files, browser cookies, registry, and duplicate files. Plus, you can use TotalAV to optimize your system boot time and uninstall unused applications.

Given that both ESET and Microsoft Defender lack device optimization tools, this round ends in a draw. If you need an antivirus with many optimization features, TotalAV is your best bet.

10. Other Features — ESET Offers More Extra Features

ESET and Microsoft Defender both offer extra features, but you’ll get more with ESET. These features include:

• Webcam protection — protects your webcam from abuse and access by unauthorized apps.
• Secure Data — allows you to create a virtual encrypted drive on your computer or external drive to store sensitive information.
• Email and Anti-spam protection — scans your emails and blocks spam messages and phishing links.
• Anti-theft — helps you track your device if it gets stolen.
• Bank and payment protection — creates a secure browser that protects your data from theft and misuse when performing financial transactions.

Microsoft Defender offers:

• OneDrive Cloud Backup 5GB — back up your files (up to 5GB free and more upon upgrade) ensuring you don’t lose any of your important files.

ESET beats Microsoft Defender here as it offers more extra features that provide additional protection to your device.

11. Device Compatibility — ESET Is Compatible With All Major Operating Systems

ESET is compatible with most platforms, but Microsoft Defender is only compatible with Windows. While I found Microsoft Defender easy to use, its lack of support for other operating systems makes it unreliable for protecting all your devices.

ESET is compatible with:

• Windows (Home Server 2011 64-bit, 7 SP1, 8.x, 10)
• macOS (10.12-11)
• Linux (LSB 3.1, GTK+ 2.6 or newer, GNU C Library 2.3 or newer, Debian and RedHat with kernel 2.6.x)
• Android

The installation process was straightforward — I downloaded the installer file, and it automatically completed the installation within minutes when executed. ESET’s installation size is also relatively small, measuring only 77.9MB, which is notably smaller than some antivirus software that can exceed several hundred megabytes in size.

ESET is a clear winner here as it is compatible with most operating systems. The apps are also very easy to set up, and the interface is user-friendly. In summary, ESET is the best antivirus program among the duo for comprehensive protection.

12. Customer Service — Both Antiviruses Offer Excellent Support Services

ESET and Microsoft Defender both offer excellent support options across different channels. ESET provides a range of support options that cater to varying levels of urgency, including live chat for immediate assistance and detailed guides for users not in a rush. I discovered that all 4 support options were easily accessible, and I was able to obtain useful information for any issues I encountered.

To test ESET’s live chat, I sent a chat and I was quickly transferred to an agent who answered my questions satisfactorily in less than 2 minutes. The email-support option didn’t disappoint either as I got a detailed answer to my question within 24 hours. Even better is that ESET offers support in 36 different languages, including English, Spanish, and French.

Microsoft Defender’s support is one of the areas the antivirus excels. Within minutes, the live chat feature provided me with all the assistance I required. Additionally, the program offers a valuable knowledge base, how-to videos, and telephone support if necessary.

In my experience with Microsoft’s live chat support, the agent requested my phone number in case the chat got disconnected so they could call me back. I found it thoughtful of them to take that extra step and ensure that they can still assist me even if the chat connection fails, something that not many antivirus programs provide.

Overall, both ESET and Microsoft Defender offer fast and responsive support channels. So, if you run into any issues when using the programs, you should be able to get them sorted in a few minutes through the different available channels.

13. Price — ESET’s Premium Plans Provide Excellent Value for Money

Microsoft Defender is only available free for Windows devices. Unlike Microsoft Defender, ESET has premium plans with excellent value across different devices.

ESET offers 3 main plans for Windows (NOD32 Antivirus, Internet Security & Smart Security Premium), 2 plans for Mac (Cyber Security & Cyber Security Pro), and 1 plan for Android (Mobile Security For Android).

The available features across the plans include:

• Malware, ransomware, and anti-phishing protection
• Gamer Mode
• System cleaner
• Antispam
• Firewall
• Webcam protection
• Network attack and botnet protection
• Banking and payment protection
• Parental control
• Password manager
• Anti-theft

While ESET offers different features across multiple devices, it comes with a few limitations. One of the downsides is that each plan only covers 1 device by default. So, if you need to cover more devices, you will have to pay extra, which can quickly add up.

Among all the plans, I recommend the Smart Security Premium package. It is the most feature-rich plan, and protects Windows, Mac, and Android devices, detecting even zero-day threats. It also comes with a password manager, which gives you unlimited password storage.

Given that only ESET offers a premium plan, it naturally wins this round. However, while ESET provides valuable features across its plans, I find it limiting that it only supports 1 device by default. Other antiviruses like Norton and Bitdefender give you coverage for at least 5 devices, even on the basic plans.

Try ESET risk-free for 30 days

14. Free Version — Only Microsoft Defender Is Available for Free

Microsoft Defender is free for all Windows users. It comes preinstalled with all its antivirus features when you launch a Windows 10 or 11 device. Although Microsoft Defender offers adequate protection against malware threats, a free antivirus program like Microsoft Defender has several limitations.

One downside is that it often doesn’t provide comprehensive protection against novel threats. Plus, it lacks essential features like VPN, password manager, and other internet security tools necessary to protect you online. That’s why I usually recommend opting for a premium antivirus like Norton 360 which starts for as little as $$$$€€€€€€€29.997.9324925.0819.9924.9929.9927.7929.9929.9930.47 per month.

15. Money-Back Guarantee — ESET Offers 30 Days to Test the Service

Microsoft Defender offers a free antivirus with basic features. So, it doesn’t have a money-back guarantee. On the other hand, ESET offers a 30-day money-back guarantee for all of its plans. The process is straightforward – simply send an email or make a call to customer support. It’s worth noting that you’ll need to contact the ESET region where you made your purchase.

When I contacted UK support, I received a response within 2 days, which included immediate approval without any further requirements. I’ve encountered several antivirus programs that require additional justification for a refund, so this was a pleasant surprise. The refund was processed and back in my account within just 1 day.

And the Winner Is… ESET

After pairing ESET and Microsoft Defender across different areas, ESET emerged as the clear winner. It beats Microsoft Defender in malware detection rates, ease of use, security, and extra features. In addition, ESET provides comprehensive protection for all major operating systems, which isn’t the case for Microsoft Defender.

• Virus Scanner — ESET

• System Performance — ESET
• VPN — No winner
• Parental Controls — Tie
• Firewall — ESET
• Password Manager — ESET
• Gaming Mode — ESET

• Other Features — ESET
• Device Compatibility — ESET
• Customer Service — Tie
• Price — ESET
• Free Version — Microsoft Defender
• Money-Back Guarantee — ESET

Microsoft Defender is free and comes with adequate features for protection against malware threats. With near-perfect malware detection scores, a decent firewall, and above-average parental controls, Microsoft Defender isn’t all that bad. However, when it comes to your overall protection from the latest threats, Microsoft Defender may not be suitable for the job, meaning you’ll need a premium antivirus like ESET.

To test it for yourself, I recommend signing up for ESET with the money-back guarantee. This way, if you are not satisfied, you can receive a full refund.
