Recently I started using "Bitdefender Antivirus Plus". Now, every day, when I first use my computer, I get the following message: Suspicious connection blocked Feature: Online Threat Prevention firefox.exe attempted to establish a connection relying on an unmatching security certificate to t.sgc.io. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one. Add to exceptions Is this something I should be concerned about, or should I "Add to exceptions"?
