Hi ,
I'm Dyari. Thanks for reaching out.
That message is not a real Windows virus warning. It is often a fake pop-up. Do not click the pop-up, do not click “Scan”, “Remove viruses”, “Call support”, or enter payment details.
Open Edge or your default browser> Temporarily disable all installed extensions.
Then, go to Windows settings > Apps > Startup > Turn off anything suspicious or unknown.
After that, open Windows Security > Virus & threat protection > Scan options > Full scan >Run a Full scan. If you are using third-party security software, run a full scan with it.
Stay safe
