Someone "Spoofing" My eMail Return Address From OP

Hello Robert11

VistaKing is no longer on this forum.

I have moved your post to the security forum where hopefully other members can provide you with guidance on your issues

I've emailed Jacee to follow up on this.

Jacee : Roberts original original thread of the problem:
eMails Being Sent By Themselves ?

Hi Robert11, first of all ... using a different computer, change all of your passwords!

Next, make sure proxy settings are disabled:
1) Under “Tools” in the browser tool bar select “Internet Options”.
2) In the “Internet Options” window that pops up, click the “Connections” tab at the top.
3) Click “LAN Settings” near the bottom of the “Connections” section.
4) If the “Proxy server” checkbox is marked with a check, click it to deselect/uncheck it.
5) Click “Ok” to close the “Local Area Network (LAN) Settings” window.
6) Click “Ok” to close the “Internet Options” window.
Reboot
Make sure "Proxy server" is still disabled under your LAN Settings.
