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

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.

@Elaine L. Mills ,

Welcome to the Bitdefender Forums. The original topic is over a year old and refers to a different issue. Perhaps a Moderator will open this as a new topic for you.

VirusTotal shows the link to be clean, but when I tried to access it via Chrome on a Windows 11 computer, all I got was a blank screen with the words "Not a file" in the top-left corner. It seems that the site is an advertising server site that is sometimes associated with mild malware (browser redirections). If you do a Google search on the URL, you will find an article on the subject at MalwareTips dot com.

Bitdefender does not block the installation of browser extensions because they are installed by the user.

What is the source of the "refused to connect" message? Does it come from Google, as I expect, or from Bitdefender? If it is Google, then the site may be unavailable.

Please keep us posted. Have a great day.

Regards,

Phil
