I have Norton running and a couple times every minute it displays the message "Scanning message 1 of 1".
Often, a second warning message appears; "Your email message was unable to be sent because your mail server rejected the message:"
I have had Spybot running on the machine since new but had to unload it yesterday when I upgraded Norton to try find this problem. Spybot, Norton and Trendmicro.com have been unable to stop it.
I have attached a Hijact This log file (hijackthis_mtk.txt)
Thanks to anyone who helps. I'm baffled.
