Microsoft has just broken Windows 10’s antivirus protection

Do NOT trust Microsoft to protect your computer. This is why I recommend people use another antivirus and spyware detector. I recommend Avast, and Malwarebytes, which work well together. Available for PCs, Macs, Android and iOS phones and tablets. Both are free but are also inexpensive if you want automatic scans. They are on my devices.
