I'm am currently using a different PC, from what follows. I have an idea what's wrong; but, I need to confirm my methodology in the Norton Community.
I use web-mail exclusively, and I've got an email from myself, in my Spam Folder, that I didn't sent: I've had a couple previously. I regularly change my password; so, it's time to track down the problem. There're no other apparent problems.
I would be grateful if someone would list the current links to all the external scanner tools, suitable to get to the bottom of the problem: whatever is available, and how to set them up. So,that I can do a work through, and localize my problem.
CHEERS !
Be safe out there ! AK
