Is Windows Defender enough to protect your PC?

We all know the importance of antivirus software; however, it can be difficult to know which product is best. A quick online search establishes there is no shortage of antivirus programs touting their ability to stave of rogue software.

If you are a Windows 10 user, you may not have to worry about choosing a third-party program as your desktop has Windows Defender antivirus software built-in.

Besides the fact that this program is free and already installed, you may wonder whether it is effective or powerful enough to protect your PC. Let’s find out.

Is Windows Defender good enough protection?

Native to Windows 10, Windows Defender is, by default, enabled and works behind the scenes. In addition to performing background scans, this software will automatically scan downloads, open programs and provide new Windows Update definitions.

Advantages of Windows Defender include a user-friendly interface, it doesn’t bring bloatware and it requires fewer system resources than most antivirus programs. Testing indicates Windows Defender is a reliable antivirus program and is among the best in identifying threats.

Even with its numerous advantages and reliable reputation, Windows Defender falls short when protecting your system from malware, ransomware and zero-day attacks, leaving your computer vulnerable. For this reason, it is recommended you increase your efforts against cyber threats with the addition of an anti-malware program.

The addition of malware creates a powerful combination

Most assume an antivirus program is all the protection they need against widespread threats; however, the reality is that this approach is not enough. To help ensure your system is safe and secure against online dangers, it is essential that you combine anti-malware with your antivirus program.

There are plenty of top-notch anti-malware programs including:

If you want to test any of the top-contenders, most offer a free version or trial.

Malwarebytes is often recommended here at This award-winning program offers a premium yearly subscription for $39.99, which covers a single device, and $59.99, which protects three devices.

In addition to its ability to detect potentially unwanted programs (PUPs) such as adware or junkware, Malwarebytes contains anti-ransomware and an anti-exploit feature that prevents hackers from targeting weaknesses in an application or system. One common exploit is a zero-day attack, so make sure you’re protected.

Although Windows Defender and Malwarebytes are useful individually, the combination of the two provide a robust defense against viruses, potentially unwanted programs, spyware and malware.
