Aye, wrong forum, but MSE isn’t available for Windows 10 (Windows 11 if it’s a spanky new laptop the OP has). The built-in antivirus in Windows is now called Defender, definitely sufficient for home use.
Work laptop though I wouldn’t use a free AV solution, I use Webroot AV - small footprint, unobtrusive, it’s basically everything Norton isn’t 😂
If it has to be free though OP, I’d go with Malwarebytes.
Unless it’s a Mac, then I have no idea as I’ve rarely had cause to use one.
Having said this, if you are interacting with companies/clients online, check that they don't require that you use a specific product. If you work for a company with an IT department check with them for guidance.
