My household recently moved from AVAST antivirus to BitDefender. Over the last several days, my wife's Outlook 2024 and my Thunderbird email clients have collected numerous emails from my email server that show a blank "subject line" and no "from" address. Also the html is changed to plain text which make the emails very difficult to read! We tried turning off BitDefender's "antispam" and its email "on-line threat protection" and the problem continues. When I temporarily remove BitDefender, the problem seems to go away. This is unacceptable for us! The emails in question are/were sent to us from "good" sources such as public television and the Tulsa World newspaper's master gardeners.
