Cell Phone Viruses

  far, and do very little damage.

  a computer virus.
• It is an executable file that infects a device
  and then copies itself to other devices
• Spreads through internet downloads, MMS, or
  Bluetooth

• Only smartphones are at risk.
• User has to agree at least once, sometimes twice
  in order to run the infected file.
• A virus might access and/or delete all of the
  contact information and calendar entries in your
  phone.
• Worst case scenario? It could lock up certain
  applications or crash your phone completely.
• To protect yourself, never open anything that you
  dont know what it is, and check security updates
  regularly for filenames you should watch out for.
