You mention that it appears to be scanning outgoing messages when you aren't sending them..Have you run a full system scan using Norton..And just in case, get a "second opinion" by running either, or both of the free online scanners at the links below:
Housecall Online Scanner
Panda Online Scanner
Another good, FREE, tool for scanning your computer for malware and trojans is at the link below. I recommend downloading, installing, updating, then running the program.:
Ewido Security Suite
Many users don't really like the outgoing scanner so they turn it off. That's a personal choice, but the link below will give you the "How to":
Turning on or turning off email scanning in Norton AntiVirus
System specs: Dell 8200 w/ 256 RAM & 40 gig drive, Windows XP, continuously attached flash drive.
MY PROBLEM: My Norton activates and opens a window out of the blue lately indicating that it is virus-scanning outgoing emails even though I am not in the act of emailing anyone. Presently, I don't even use Outlook Express and have not set it up again since I had to reformat my drive and just use web access right now. So, I cannot track outgoing emails via Outlook Express.
I am baffled and concerned. How can I determine the cause and source of these emails? Does anyone share similar experiences?
