Hello

The Subject of this message  is in my add/remove panel and wanted to know if this is because I chatted with Norton?

If so, can I remove it?

If I may, do you know where it is written that idle time full scan runs once a week? I saw it once in the Norton Security Suite but cannot find it again and I need it for reference in writing to someone.

Lastly, I would like to change my user name because it is difficult; I did not know spaces were not permitted so the one I use can be confusing or misread when I log in infrequently.

Thank you for your help.
