Someone clicked on my username on Microsoft Community Forum and found my personal email address they posted my email address on another forum. I was trusting and never had any problem on the Microsoft Forum. I did post it in an area that was "public". Now it seems I will need to change my email address. I have removed my info from Microsoft Forum. Do I need to do that here? I will also be updating my email here. Any help or advice would be appreciated. I know not to open attachments from strangers. I have the Bing mail app on my Windows 8.1 system. How effective is Norton at screening my email? I might want to change my user name as well.
