Threat Secured...URL:Phishing

Good morning. I am a Dentist and we use Avast Business for all our workstations. This morning when trying to login in an Insurance Site to verify insurance benefits, we received a message stating the connection was aborted because it was infected with URL: Phishing.

The site in question is hxtps://signin.mfa-sunlife.com

Is this a false positive or legit?

You can use this link to ask AVAST to review the website: https://www.avast.com/en-us/false-positive-file-form.php

Hi,
detection will be fixed in next update.
Best regards
Lukas
