Various sources have said that somewhere between 3million and 10million systems have been infected already.

Typically, users gets a Windows alert saying that there is no network provider. However users still can ping the computer name or IP Address. W32.Downadup.B also creates autorun.inf file on all mapped drives and automatically executes it when the drive is accessed. Then the virus monitors for other computers that are connected to the infected computer. W32.Downadup.B creates autorun.inf as soon as other computer becomes accessible.
