Every 20 minutes or so I get a notification from Bitdefender Online Threat Prevention module indicated it has blocked a suspicious connection. This has only started about 2-3 days ago. The only information the popup indicates is:

"firefox.exe attempted to establish a connection relying on an unmatching security certificate to gitcdn.xyz. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one."

I performed a full system scan and found nothing harmful. Anyone know what this is or how I can fix it?

Isisombululo esikhethiwe

Thanks for the info, Fred. I looked into the problem a bit deeper (it wasn't cause by Malwarebyte and still running the other tools to be safe) and found a few posts on Reddit that say it's a Firefox add-on, likely uBlock Origin, that is having some trouble updating its database. Other users running Bitdefender are having the same error pop up these last few days.

You may have ad/mal-ware. Further information can be found in this article; https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware?cache=no

Run most or all of the listed free to use malware scanners. Each works differently. If one program misses something, another may pick it up.
