NASA computer infected by W32.TGammima.AG

The USB flash drives infected the computer in NASA by a virus that is called W32.TGammima, that is basically a worm and the scientists at the centre said that no computers in the station should have autorun enabled to make the worm ineffective.

These worms spread by USB flash drives and other removable media files. Windows generally starts autorun as the disks are inserted but the machines should disable autorun to avoid infection.
