Is Antivirus Still Essential for Windows 10 Users in 2025?

As we step into 2025, the digital world continues to develop at an alarming pace. Cyber threats have evolved, becoming more sophisticated and harder to detect. Ransomware attacks, phishing scams, and spyware are now commonplace, making it imperative for users to remain vigilant. While Windows 10 has built-in security features, many users still question whether they need additional antivirus software.

Windows 10 comes equipped with Windows Defender, which provides real-time protection against malware. However, experts argue that relying solely on this built-in feature may not be enough, especially for those who engage in online activities that expose them to higher risks. Let’s explore the arguments for and against using separate antivirus solutions alongside Windows Defender.

Arguments for Antivirus Software

Layered Security: The primary argument for additional antivirus software is the concept of a layered security approach. Using both Windows Defender and third-party antivirus software can create multiple lines of defense against various forms of malware. If one system fails, the other may still protect the user.

Comprehensive Scanning: Third-party antivirus programs often offer more comprehensive scanning options and can identify threats that Windows Defender might overlook. They employ various techniques, including behavior-based detection, to catch emerging threats.

Advanced Features: Many antivirus solutions come with added features like VPN services, password managers, and parental controls, enhancing overall digital security. These functionalities go beyond simple virus detection, providing a more holistic security suite.

Customization: Third-party antivirus programs offer greater customization options, allowing users to tailor their security settings based on personal needs. Users can schedule scans, select specific files or folders to monitor, and adjust shields for added security.

User Support: Traditional antivirus software often includes customer support, providing users with expert assistance during issues like malware infection. This can be especially helpful for less tech-savvy individuals who may struggle with complex security problems.

Arguments Against Antivirus Software

Overlapping Features: Critics argue that many of the features provided by third-party antivirus programs overlap with those offered by Windows Defender. This redundancy can result in system slowdowns and conflicts between the two software packages.

Costs: Quality antivirus solutions often require annual subscriptions, which can add up over time. For casual users who engage primarily in safe browsing practices, the expense may not justify the perceived benefits.

Resource Usage: Third-party antivirus applications can consume valuable system resources, impacting overall performance. For users with lower-spec machines, this can lead to frustrating slowdowns.

False Sense of Security: Relying too heavily on antivirus software can result in a false sense of security. Users might neglect safe browsing practices or fail to keep their software up to date, exposing themselves to risks.

Built-in Tools: With Windows 10 continuously updating its security features, many users find that the built-in tools are sufficient for their needs. Features like the Windows Firewall and SmartScreen filter effectively mitigate risks for average users.

Comparison of Antivirus Solutions

To better understand the differences and features of various antivirus software, here’s a comparison table of some popular options available in 2025:

Antivirus Solution	Comprehensive Scanning	Additional Features	User Support	Cost
Norton	Yes	VPN, Password Manager	24/7 Support	$39.99/year
McAfee	Yes	Identity Theft Protection	Live Chat Support	$49.99/year
Kaspersky	Yes	VPN, Parental Controls	Email Support	$59.99/year
AVG	Yes	File Shredder, VPN	Community Forum	Free $69.99/year

This table summarizes key features of various antivirus solutions available in the market. Each software offers a different level of protection and additional features, catering to various user needs and security preferences.

Conclusion on Antivirus Software Need

As we assess the need for antivirus software alongside Windows 10’s built-in protections, it is essential to consider personal usage habits. Users who frequent high-risk environments—such as torrent sites or those engaged in online banking—may benefit significantly from the additional layer of security. In contrast, casual users who practice safe browsing may find sufficient protection in the built-in features of Windows

The decision ultimately rests on the balance of convenience, cost, and the specific security demands of individual users.

It’s true that certain antivirus programs can indeed cause your computer to slow down, especially noticeable when a full system scan is in progress. These scans often require considerable processing power and memory usage, which can lead to a more sluggish performance overall. When your device is busy analyzing files and applications for potential threats, you might find that tasks such as opening programs or browsing the web take longer than usual. This is particularly frustrating when you’re in a hurry and need your computer to respond promptly.

However, the level of impact an antivirus has on your system largely depends on the software you choose. Not all antivirus solutions are created equal; some are designed with performance in mind, ensuring that they provide robust protection without compromising speed. By doing a bit of research and selecting an antivirus program that emphasizes optimization, you can find one that strikes a balance between keeping your computer safe and maintaining its efficiency. In this way, you can enjoy peace of mind without sacrificing the performance that you rely on daily.
