MDMSetPe.exe
(Aztech)
System Tray configuration icon for Aztech modems. The icon enables you to set up the country for the modem, and the modem audio mode. Through an oversight the modem drivers installation utility installs this configuration icon in the System Tray but does not install an alternative way of starting it up in the Aztech program group that it creates.
Recommendation :
Harmless. Once you have configured your modem you can choose to keep the icon in the System Tray, or you can choose to disable it with Startup Manager.
