Windows Defender has become the default antivirus in Windows OS, being the best for now as an antivirus that has been provided in the OS. then juxtaposed with Malwarebyte which you think to be the best. I believe that Malwarebyte has many advantages to being able to protect a device from malware.

I don't trust any company blindly, this is just the protection I need. I use Dual Antivirus configuration which is more productive and safer.
Malwarebyte or other antiviruses have their respective advantages. All depends on the choice of each individual, the most important is the main security and database updates that are always done.
