I am having a very strange problem. I currently have Norton Antivirus 2005 installed (and have so for months). I have the scanning of outgoing emails feature turned on, so when I compose and send a message from Outlook it is moved to the 'Sent Items' folder and then Norton relays the message (showing its progress near the systray in a popup). For the past couple of months my PC has been sending emails by itself occasionally. They are not being sent through Outlook but the Norton outgoing email scanner does pop up briefly to let me know it is scanning an outgoing message.
I have done searches by date for files last modified and accessed and can see nothing suspicious. I am running Norton AV 2005 with all the latest updates and this PC also does weekly virus scans by itself. I have run Adaware as well and found nothing that strikes me as being odd. Also the smtp server I use for relaying is my own (located on a different PC, not on the same network). I have checked the logs on the server and these messages are not being relayed through my server.
I'd like to stop this from happening (or even confirm that it is indeed happening) but more importantly I'd like to know what is being sent and to whom. Does anyone have any suggestions on how I can track these outgoing messages or locate the source application which is sending them?
