[Virus Error] inserted in front of the email subject line
This just started happening. Thought it was because the of the recipients' email's treatment of attachments but no. I just replied to an email (no attachments) and the recipients (all of which were in the original email) now get [Virus Error] inserted in front of the email subject line.
This only happens when I use my iCloud email on my PC which has a good (and paid for) AV program.
I have several accounts - 1 is with my ISP, the rest are private, gmail or yahoo. None of them produce the same problem or any virus warnings to recipients from those accounts. I'm using Outlook 2016.
What's going on Apple/iCloud. I changed my default email to iCloud to avoid problems with my ISP and now I have new problems.
