It's not that there's a problem with Windows Defender. It's that we all have our personal opinions about what we feel is best for us.

Defender is now very good, but others are even better and use less RAM and CPU time. Each to his own.

Looking at only RAM is not enough for performance tests. Here's a sample of what's done with the latter:

AV-Comparatives released the Performance Test report September for consumer security products under Microsoft Windows 10.
