I run XP so have a thing called Windows Mesanger sitting in my system notification area, (tray - by the clock). It is not signed in, and has a little white cross in a red circleŽon it's icon.
It normally sits there doing nothing. At reboot, I get a box pop up, then a second box asking me to enter what name I want to use. I usually delete the window and close the box.
Normally, end of story until next reboot. Today, that box and the second one asking for a name has been popping up every 10-20 minutes or so. It is a damned nuisance.
If I try to close this app, it tells me that other software is dependent upon it without saying what.
Could this be due to someone trying to contact me through this service? I don't know, I never use anything like that.
