Thank you for the basics. I'm aware of most of the basics. I have Norton
Anti-Virus and Security. I keep it updated on both counts every other day.
I use Windows XP. I scan for Windows updates at least once a week and
whenever a bug is found.
I have a very specific issue which has yet to cause me performance or
missing data problems.
As I mentioned, I have entries under Entire Network which shouldn't likely
be there. One appears to be the person who has access to my cpu. The other
a government website.
I'm trying to secure my computer from outside connections that shouldn't be
Doing the best I can at absorbing the necessary information about security.
