Online Threat Prevention
firefox.exe attempted to establish a connection relying on an unmatching security certificate to wxcharts.eu. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one.
What is this and is it really a potential threat? I am using Cumulus version 1.9.4 and the latest Firefox browser. My anti-virus software is Bitdefender. Why am I getting this? Is it coming via something other than Cumulus software?
