I have Microsoft Office 2010, which includes Outlook 2010. I have three components installed from Avast: File Shield, Behavior Shield, and Web Shield. About a week ago I decided to increase the sensitivity of File Shield and Web Shield by enabling “Test whole files.” Since then, I have been getting a send error with Outlook 2010 when I try to send an email. The error discontinued when I disabled “Test whole files” in File Shield, so there’s some sort of issue between Avast and Outlook 2010. Attached are screenshots.
