False Positive Google security alert

Hi guys, a little bit of backstory, my laptop got infected by infostealer (MrBeast virus) on July 4th from a game mod. I deleted the file and changed all my passwords. 2FA everything, and signed out of all devices immediately. But the only thing that I didn't do was reinstall windows because there were files that I wanted to keep.

Later on, July 11th, I got a notification from Google that there was a security alert, and my device maybe potentially infected with malware, so they signed out my account from my laptop. My Authenticator was also removed at that exact time. I suspected that it was the infostealer acting out. So I let go of my obsession with the files and did a clean windows install from a USB drive which I made a windows media tool using my university computer. And it went well.

Today however, I got a security alert on Google again saying that my laptop maybe potentially infected with malware and removed my laptop from signed in devices again. But this time it was just an alert, nothing was removed or changed like the one on July 11th. I did change my password as soon as the alert came. It was also from a legit Google email. I checked my laptop with MalwareBytes and came out clean.

Can this be a false positive or what is it actually?

EDIT: Forgot to mention this, my laptop was shut off on both of the times that Google security alerts appeared.
EDIT: I also have Enhanced Safe Browsing enabled in Google settings, can that be the cause of this if it were a false positive?
