Yesterday I opened Thunderbird to find that it was trying to download 8205 emails. 15 emails actually downloaded, there were no messages in SPAM folder. The notification at the lower right showed 300 more had 'downloaded' before I shut off the internet, went into Safe Mode, ran a virus check to find no threats found. No SPAM was recorded in Thunderbird when I went back online. There were, however, several files with large attachments so I don't know if this is a glitch regarding data vs. actual number emails because when I checked for updates (see attachment) I discovered that since Version 115.4.2 I HAVE NEVER BEEN NOTIFIED OF UPDATES OR *FAILURE* TO UPDATE. AUTOMATIC UPDATES have been turned off and will remain turned off due to nearly dialup speed lack of bandwidth. I will abandon Thunderbird for having a fatal programming defect before turning on automatic updates. My actual email provider did not show 8205 additional emails so I am concerned about a possible malware backdoor. Today 15 emails downloaded while the little notice at lower right said it was trying to download 113 ghost emails. I shut off Thunderbird and came here to post the problem. I will update Thunderbird, but need to know if there is a temporary file cache or some other hideyhole that the ghosts (or some attacker) might be storing godnosewhat so that I can either quarantine or delete them?
