MyFTP.exe stopped by Firewall

I've just installed a new PC running WinXP - also installed System Suite 7 including a firewall.

Periodically (every 30 min or so) Windows seems to be trying to access an Internet ISP address via a program called MyFTP.exe. The firewall gatekeeps this and queries me whether I want to allow the program to do this.

What is MyFTP.exe and what is it doing? Is this some routine way Windows is updating itself? Maybe just checking the time or something?

Thanks - LH
