Glad to hear from a Linux guy. Many people would prefer just using the Windows defender that comes by default along with Malwarebytes Anti-malware as a second layer of defense. I recommend you too this if you have a laptop with good specs (I hadn't searched about your laptop), cause Defender reportedly has a considerable impact on the performance (like high RAM/Disk/CPU usage). If you would like to try something more, then consider the following alternatives:
BitDefender free has less impact and requires minimal/completely no maintenance after installation. This might be suitable if you dislike wasting your time hanging around the AV. Furthermore, BitDefender offers top notch protection this day.
Secondly, Avira offers a top notch protection too. It reportedly has a little impact on the performance though the company says it doesn't.
Finally, Avast, the most popular AV, is a choice too. But, it has a low detection score than the formers.
Besides, a good Anti-malware software like Malwarebytes Anti-malware is also recommend.

Hope this helps.
