This is what I tell my family and friends. Whenever I help someone upgrade to Windows 10, or work on their computer, I tell them to just use Microsoft Defender. I've also read various reports of security problems with AV software, so I'm not comfortable recommending anything third-party. Defender + uBlock is a pretty simple and effective combo.
