I don’t care how good the credit monitoring and identity theft protection is for Aura, as a software package and company, it sucks. Never believe those “best of” and comparison articles. 99% of them never bother testing with email, especially sending email via either Thunderbird or BetterBird. If they recommend Avast or AVG you know they didn’t. You can find this here.

Yep, that’s from the official BetterBird support page.
Anytime you are on a Windows computer and cannot send email from your local email application, close the email application, turn off your antivirus, wait five minutes for background tasks and caches to clear, open email client and try sending again.
How hard can it be?
I mean it seems like “antivirus” software companies are popping up every week. Not surprising since ClamWin is free, Open-Source antivirus software. Most likely all the new ones are starting with it. ClamWin doesn’t pooch sending email so how is it the knock-offs do? Yes, yes, yes, you wrote your AV software starting with a clean sheet of paper, never having looked at any other AV source code . . . yeah right.
Infuriation Without Limits
Keep in mind it is not just sending. Those who type really long emails, or walk away in middle of email then return must get used to seeing this.

Yeah, nothing breaks your concentration like the timed save to drafts folder gagging. At least the following only happens when you hit send . . . nearly ever time you hit send.

Of course, that’s after you are greeted by this just starting BetterBird or another email client.

Management Sucks!
For weeks I was the good soldier. First I tried to use Linux for everything where I wouldn’t have Aura to deal with. Second, I dutifully used the diagnostic app. You can find it on a few menus, notably the Preferences menu on the left of the main dialog.

when you choose to open the diagnostic app you get the following.

Choose “Other issue.”

You “Start Session” then you run through whatever activity (sending email) multiple times capturing copious quantities of information about the error. Then you stop the diagnostic session and you get an option to “send the information to support.” After it successfully uploads to their server you get an ID for that upload and told to use that ID whenever you talk to support.
Nobody is monitoring that upload
Some little girl called about a week ago or so. I thought she was calling from support after they isolated the issue. No, she was from sales/marketing. I Ass-U-Me it was a time-share up-sell attempt. Bad day to be her. I had just spent half an hour trying to send one (1) email. I read back the list of IDs I had, yes, I kept a list in a file on disk, and she frantically clicked at a keyboard claiming to be looking up trouble tickets.
Nadda.
You don’t bake a diagnostic system like that into a product without assigning the task of monitoring the uploads to someone. It’s not even a difficult task since you wrote the upload system. Configure it to send an email to a distribution list containing all your technical support staff.
Summary
If antivirus for a given platform is “free” and not Open-Source, you are the product.
Feels like no antivirus vendor tests with email clients anymore. I’ve had most every one. Norton, Macafee, Bitdefender, Avg, Avast and a few I can’t remember right now. Same shit, different logo. Most of these companies believe they can make up for sub-par software by providing identity theft services. For some customers, maybe.
I’m not stupid enough to own an iMbecile phone though.
Fools put banking and other payment information on them. I saw someone earlier this week at a local restaurant waving there phone over the credit card machine. Yeah, you deserve to have everything you own taken. Read the previous link and pay attention to the discussion of Pegasus and GRAPHITE.
The only solution is to not run Windows . . . any version.
I’m slowly but surely getting rid of clients requiring me to run that OS. You should too.
