I frequently get this notification from my Bitdefender Total Security:
Suspicious connection blocked
Feature: Online Threat Prevention chrome.exe attempted to establish a connection relying on an unmatching security certificate to contents3.00110.citi.com. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one
The question I have is this a possible false positive? I do have a browser tab open to citi.com and the site looks legit. Chrome browser says the certificate is valid. But every time I get this notification I start to wonder if maybe there is a problem. I don't want to add to exceptions if it is a ligament malicious site.
