Hello

Defender is not sufficient protection

you need to install antivirus protection

you would have had a free trial for a new AV subscription

This program must be removed before installing another AV

read this information on the Defender:

·                         If you use microsoft security essentials avg avira mcafee norton etc they disable the vista version of windows defender by default

the basics of Microsoft security has its own version of windows defender

and other anti-virus programs use their own particular type of application to scan for spyware and malware

It of nothing to worry and is the default action, which is designed for them to do
