I Keep Getting A "Suspicious Connection Blocked" Notification And I Don't Know Why. Any Help?

john5235

Multiple times a day, and constantly when using chrome, I get the notification:

Feature:Online Threat Prevention

chrome.exe attempted to establish a connection relying on an untrusted certificate to wpad. We blocked the connection to keep your data safe since untrusted certificates are issued by unrecognized Certificate Authorities.

I have also received the same notification for microsoft edge, and I don't know why, I've restarted my computer and internet multiple times as well as updating BitDefender.

If anyone has a solution or explanation I would be very thankful.

Hello.

This situation is caused by the fact that the website in the notification has an expired certificate. This doesn't necessary involve malware. The “Suspicious connection blocked” notification is triggered by Bitdefender’s Online Threat Prevention module whenever there is an attempt to access an HTTPS domain that has security certificate issues. Unlike HTTP (Hypertext Transfer Protocol), HTTPS (safer HTTP Secure standard, HTTPS) is encrypted using Transport Layer Security (TLS), securing communications between your computer and the websites you visit.
