We all know that Windows Defender lags behind when it comes to extra security-related features. But it is worth mentioning that Windows Defender has got pretty much all the basic features that work pretty well. It can run various types of scans likes full scan, custom scan, quick scan, and offline scan. It also provides you with real-time protection and scans every newly downloaded file before you decide to use it. Other features worth noticing are the built-in firewall and the Smart Screen Utility.
On the other hand, Avast Free Antivirus has got advanced security features. Usually, these features come with premium suites of other Antivirus Software. Just like Windows Defender, Avast has also got a variety of scans which include Smart Scan, Full Scan, and boot-time scan. The Wifi-Inspector tool helps you in finding suspicious Wifi-Networks that can harm your system. The Software Updater updates outdated applications automatically. The Gaming Mode lets you enjoy your games without any interruption. Email Protection, Password Manager, and Rescue Disk are some of the other features that make Avast much better than Windows Defender when it comes to Security-Related features.
Windows Defender vs Avast Antivirus: Resource Consumption
Every Antivirus should provide with real-time protection while consuming as fewer resources as possible. To find out which among Windows Defender and Avast Antivirus consumed fewer resources we’ll look at the tests conducted by AV-Comparatives.

Hence, it’s clear that Avast is the winner when it comes to protecting your system against threats.
Windows Defender vs Avast Antivirus: User-Interface
The Window Defender’s UI is much easier to navigate and grasp. It’s highly user-friendly and I found it really easy to operate.

So, according to me, Windows Defender has a much better and simpler UI than Avast.
