Nis 2005

I have gotten small pop-up from NIS 2005 in lower right of screen that read something like "a program is trying to connect to a DSL." It happened on my desktop a while ago with program listed as "Microsoft," and on my notebook with program listed as "AOL." I usually click on OK, but when I did click on OK, the pop-ujp kept coming back several times, until it eventually stopped.
Would anyone know why this is happening, and why it keeps popping-up over and over again?
Thanks for any help.

(We are senior citizens and have really gotten used to NIS 2005 and enjoyed using NIS 2005 and really could not afford buying another program. And we are not too familiar with computers and installing new programs, etc.)

 

Would you know where that might be, please?
I looked in the Personal Firewall / Configure / Programs and see they are all marked Automatic or Permit All.

(As I said, when I click on the OK, the pop-up will come right back up, and so on.)

Thank you.
Alice
