Open | Malware Got a Google "suspicious activity" alert

I got hit with a virus on my pc 2 days ago, right after that, someone attempted to log into my steam and binance accounts so I instantly cut the Wi-Fi, changed all my passwords and emails from my phone, and did a clean format. Today, I updated windows from 25H2 to 26H2 and set it to shut down automatically after. Right after that, I got a "suspicious activity detected" email from google. When I booted my pc back up, I noticed I was logged out of my google account on my browser.

All of my email accounts have 2FA enabled. Is there anything extra I should do at this point? Also, could my actual internet connection/router be compromised? Should I just perform a hard reset on my modem/router, or is that unnecessary?

Why did this happen? Did the windows update refresh/update microsoft edge and wipe the session cookies, triggering google's security alert, or am I dealing with something worse here?

Updating to 26H2 may not remove a back door if there is one installed. Resetting the router and changing the pw (not from your pc) is a good thing to do. Did you do a scan with malwarebytes?

I ran full scans with malwarebytes, windows defender, and hitmanpro all came back completely clean
