Hello Gian.
We regret any inconvenience caused.
Could you try visiting the same websites on a different web browser (like Mozilla Firefox or Microsoft Edge) and check if the threat detection pop up appears?

no only in chrome
i've done a full scan of pc, but it all ok.

also file scan of all pc but nothing found

Thank you for confirming, Gian.
We'd request to reset chrome to default settings to resolve the issue.
