A-ha! Just after posting this I found the solution. If anyone is interested the steps are:
Go to the settings tab in your avast anti-virus application
Click the Active Protection tab on the left hand side
Click the settings button on the mail shield tab (directly to the left of the blue ON button)
Click the Behavior tab on the left hand side
Under General there are 4 settings that you can check, the third one in the list says “Insert note into clean message (outgoing)” If you want the email signature in your emails, check this, if you don’t want the signature, un-check it!
