Best antivirus software for Windows 7

Following repeated waves of malware attacks, users should make sure that they’re running the best antivirus. Windows 7 has its own built-in security module, but it doesn’t provide complete protection.

While you might continue to use your Windows 7 PC, without ongoing software and security upgrades, it will be more vulnerable to viruses and malware.

Furthermore, you may believe there are no risks, keep in mind that even supported Windows operating systems are vulnerable to zero-day attacks. 

When hackers decide to attack Windows 7, as they will most certainly do, there will be no security fixes available. Using Windows 7 securely necessitates greater vigilance than usual.


Does Windows 7 have an antivirus?

Windows 7 has the Microsoft Security Essential security utility which is a forerunner for what Windows Defender is today. The utility is able to detect and block viruses and malware but is very outdated.

Microsoft stopped offering support for Windows 7 in January 2020. This means that they no longer release updates for the operating system.

That makes Microsoft Security Essential an outdated antivirus that can no longer provide what is required to keep your system fully secured. It is recommended you use a third-party antivirus that’s compatible with Windows 7 and still releases new, updated versions.

Do I need an antivirus on Windows 7?

Windows 7 no longer receives security updates and we expect the number of Windows 7-targeted attacks to grow.

Remember that, as the name implies, it only provides basic security; if you feel unsafe with your Windows 7 PC, it’s always a good idea to try software that is trustworthy and has your back while you go online.

If you want to prevent hackers from infecting your Windows 7 PC with malware, install one of the antivirus software picks listed below.

Chances are that you run Windows 7 on an older machine, which means you have fewer resources, so an antivirus with a smaller file and less resource usage is recommended.

Also, make sure you get an up-to-date antivirus. Whilst there are plenty of old AV versions available for download that are certainly compatible with Windows 7, these are not very useful in blocking current threats.

These are the best Windows 7 antivirus solutions that you can install on your PC.

As you can see, most of these tools come in three different versions: a free version, an Internet security edition, and a total security version.

What is the best virus protection for Windows 7?

Install the antivirus that best suits your needs. For example, if you need an antivirus with a built-in VPN, you can select Avira’s Total Security antivirus.

If you’re concerned about keeping your PC secure while browsing the Internet, then you should go for an Internet security-focused solution.

Also, we recommend buying an antivirus solution, instead of using a free version. As a matter of fact, free antivirus solutions generally offer limited protection against malware, leaving many areas vulnerable to threats.

Money spent on a reliable antivirus is money invested in securing your data.

Speaking of protecting your data, you can also install a great VPN software compatible with your antivirus to block third parties from tracking your online activity.

Can Windows 7 still be used safely?

Using an operating system that is not supported anymore is definitely challenging. Making Windows 7 secure is still possible, but a lot more time-consuming than it would be for operating systems that still get upgrades.

Microsoft still releases security patches for older operating systems, including Windows 7, but these are generally not enough to ensure overall protection.

The main problem is that your applications are not written to comply with today’s requirements. Not only that, but third-party application manufacturers are slowly dropping Windows 7 as well.

This means that it is way more difficult to get a basic application like a web browser or a productivity suite. You will have to make some research and find apps that are up-to-date and compatible with Windows 7.

What are the risks of staying with Windows 7?

Your PC is more vulnerable to cyber attacks when you use an outdated OS and consequently outdated software.

Windows 7 is not prepared to detect threats that did not even exist when its last service pack was released.

This leaves plenty of opportunities for hackers that can more easily access your OS, and damage and steal your data.

How do I secure my computer Windows 7?

To secure your operating system, it’s important to make sure you get updated software from secured, official sources.

This does not include only antiviruses. All your applications should come with Windows 7 compatible versions that still get frequent updates that make them less vulnerable to attackers.

Consider getting a secure browser for Windows 7, as well as a VPN that will help you protect your data. A network monitor can also help you make sure there’s no suspicious device connected to your Wi-Fi.

This has been our rundown for the best antivirus software for Windows 7. We hoped our insights helped you learn more about the operating system’s security requirements and helped you pick your best bet.
