Choosing the Right Protection: Microsoft Defender vs Avast

Microsoft Defender: The Built-in Security Solution

Microsoft Defender comes at no additional cost with Windows 10 and 11 systems. Originally launched in 2001, this security tool has evolved significantly from its basic beginnings during the Windows XP era. Today's version offers comprehensive protection as part of the Windows Security ecosystem.

For business environments requiring enhanced security measures, Microsoft offers Defender for Endpoint—a premium solution designed specifically for corporate networks facing sophisticated threats that may require expert intervention.

Avast: The Established Security Specialist

Founded in 1998, Avast has built a reputation as one of the leading names in cybersecurity, currently protecting over 435 million users worldwide. The company's merger with AVG in 2016 allowed them to combine technologies and features from both platforms, creating a more robust security solution.

Cost Considerations

While Microsoft Defender's greatest advantage is its zero-cost integration with Windows operating systems, Avast offers promotional pricing with current discounts of 50% on their Avast One package, which includes additional security features beyond standard antivirus protection.

For budget-conscious users with Windows 10 or newer systems, Microsoft Defender provides immediate protection without installation or subscription fees. However, those seeking advanced features might find value in Avast's premium offerings despite the additional cost.

unlike Microsoft's OS-exclusive Defender

Real-world testing involved both controlled EICAR samples

and live malware including trojans and adware variants

Compressed executable files were analyzed in sandbox environments

to assess detection capabilities across both security platforms

In my daily use, I aimed to evaluate the performance of Windows Defender and Avast in their continuous, always-on scanning mode. Ideally, I expected to receive a notification of any threats when I downloaded the malware samples.

One notable feature of Microsoft Defender is its ability to coexist with other third-party antivirus software, such as Avast. It achieves this by selectively disabling some of its own security features, which can be very convenient for users.

During the test, Microsoft Defender successfully identified all the malware samples. However, it required me to unzip the fourth EICAR sample before it flagged it as a threat. Despite this, Microsoft Defender effectively blocked the sample once it was unzipped.

On the other hand, Avast One did not perform as well in real-time malware detection. It failed to detect both the compressed and unzipped EICAR samples, as well as the .txt sample. However, it did manage to block all the live samples and one of the EICAR samples.

To further test, I disabled the real-time scanning feature for both software and ran a quick scan. Interestingly, both antivirus products failed to detect any of the samples during these scans.

Continuous protection requires optimizing both security and performance

In my evaluation, Avast took 186 minutes to complete a full scan, examining 1,870,000 files. In contrast, Microsoft Defender finished in just 60 minutes but scanned only 302,823 files.

While Microsoft Defender is faster, the thoroughness of Avast's scan was more impressive. A deeper examination of the system, as provided by Avast, can uncover more hidden threats, which is why it detected a higher number of potential issues compared to Microsoft Defender.

When it comes to system resource usage, there is a noticeable difference between the two. As a built-in Windows feature, Microsoft Defender consumes fewer resources. On the other hand, Avast, being a third-party application, demands more from the system. This is particularly evident when both programs are running in the background.

Performance metrics reveal notable contrasts between the two antivirus solutions. While Microsoft Defender demonstrated lower disk and memory usage during full scans compared to Avast, its CPU demands spiked higher. Independent testing by AV-Comparatives highlights Defender’s efficiency in most performance categories, though it lagged in initial file transfers and archive operations. Avast edged ahead overall but showed delays during app launches.

Feature sets diverge significantly. Microsoft’s offering integrates tightly with Windows ecosystems, providing biometric login via Windows Hello and cloud backups through OneDrive. Its family safety tools offer parental oversight for connected devices. Avast Premium Security, however, casts a wider net with cross-platform device coverage, webcam access controls, and irreversible file deletion to prevent data recovery by malicious actors.

Installation experiences differ starkly. Defender requires zero setup for Windows users, though optimizing advanced protections like ransomware shields demands manual configuration. Avast necessitates purchasing a license but simplifies deployment across devices post-purchase, with refund processing proving hassle-free in practice. Both solutions deliver swift scanning capabilities post-installation without overwhelming system resources.

Security extras tilt the scale. Avast adds niche utilities like network vulnerability scanning, automated software updates, and phishing-resistant email filters. Defender counters with native browser protections and seamless OS integration, though lacks Avast’s hardware-centric safeguards. For users prioritizing multi-device coverage and physical security layers, Avast’s expanded toolkit may justify its price tag, while Defender appeals to those embedded in Microsoft’s ecosystem seeking minimal setup.

Microsoft restricts free users to community forums,

while Avast Premium subscribers gain prioritized access

to 24/7 live chat and email assistance.

Both platforms maintain self-help repositories,

though Avast’s knowledge base addresses

a wider array of troubleshooting scenarios.

The inclusion of location-masking VPN technology

in Avast’s packages proves particularly valuable for

streaming enthusiasts and travelers needing to bypass

strict geo-blocks or surveillance-heavy networks.

While not essential for basic security,

this layer of privacy complements core antivirus functions effectively.

Despite macOS’s reputation for built-in protection,

installing Avast One remains advisable due to

emerging Mac-specific malware strains.

The software’s lightweight design ensures

minimal system impact while hardening defenses

against phishing and ransomware attacks.

Cost considerations further tilt the balance –

Avast frequently offers substantial introductory discounts,

making premium-grade security accessible without

the enterprise-level pricing of Microsoft’s advanced endpoint protection.

Both solutions demonstrate robust safety protocols,

but Avast’s proactive approach to evolving cyberthreats

and multi-platform compatibility cement its position

as the more versatile guardian for personal devices.
