Got a Scary Fake Virus Pop-Up on Google Maps—Should I Be Worried?

So, I was using Google Maps to find a business's website, and when I clicked on it, I got redirected to a scary ad claiming my PC was infected with malware. There was a Norton antivirus ad too, but I don't actually have Norton. I immediately closed Microsoft Edge without clicking any ads or entering my info. After that, I reset both Edge and Chrome to their default settings and ran a scan with Windows Defender, which said my system is clean. I'm worried that maybe I still have malware lurking on my PC and that it could have accessed my files, especially what's in my Downloads folder. I also changed my email password and secured my Edge account as a precaution. Am I okay?
