A couple of years ago I helped my next door neighbor set up her new Windows 8.1 machine, At the time, we downloaded and installed Microsoft Security Essentials for virus / malware protection.
She has since upgraded to Windows 10 and asked me to help her with a monitor-related problem today. After solving that one, I decided to look to see what anti-virus and anti-malware programs were on the machine. I looked into the Programs and Features of the Control Panel, thinking that I might find a program like Windows Defender, but I didn't find any programs that looked like they would be security related. I was under the impression that Microsoft Security Essentials had been replaced by Windows Defender for Windows 10.
Is an anti-virus and anti-malware program part of the Windows 10 Upgrade package, or will I have to find and download Malwarebytes and an anti-virus program and install them on her computer?
Thanks for the info.
