[Defender Pro] Serenity LED Lighting Site Hacked

I can no longer access my site WordPress via https://serenityledlighting.com/sll-edison and the woo commerce product pages and filter redirect to another page. I have requested my host to reload from a backup. This has happened before. I thought defender would prevent the site from being hacked. Is there a scan that can be done to identify the malware or code that is infecting the site?
