Do I still need other anti-virus , anti-malware, or web protection services when i have microsoft defender on all devices ?

Microsoft Defender is a robust antivirus and antimalware solution that provides real-time protection against various threats. It is designed to protect your device from viruses, malware, and other malicious software. Therefore, you do not need to have another antivirus or antimalware software installed on your device if you have Microsoft Defender.

If you have already installed AVG protection on your computers and Android phones, you can keep it if you prefer. However, it is not necessary to have both AVG and Microsoft Defender running simultaneously on your devices. Having multiple antivirus or antimalware software installed on your device can cause conflicts and slow down your system's performance.

In summary, Microsoft Defender is a sufficient protection solution for your devices, and you do not need to have another antivirus or antimalware software installed if you have it.

And take note of Brian's post.

Hi. I'm Brian and I'll try to help.

You do not need a security app other than Defender. Do not use AVG. That security software was found to be spying on its users.
