Wayne, thank you for information.
We are not sure about the exact issue.
In order to narrow down whether AVG is causing this issue.
Let us turn off the AVG protection.
Refer this article for disabling the AVG https://support.avg.com/SupportArticleView?urlname=Disable-AVG-Antivirus
Check for the issue again after disabling the AVG.
Keep us posted.
Hi Wayne,
We're glad to look into this & help you.
Please let us know how you access your emails. Is it through browsers or email client such as Outlook, Thunderbird?
Also, let us know the security programs (antivirus) installed on your computer.
Is there a way to have my emails come in without the word 'DISARMED' IN THE SUBJECT LINE?
we access through email client OUTLOOK. 2016
we have AVG free on our systems as security
