Keep following in mind to keep cell phone viruses away:

• Switch to Bluetooth hidden mode. If your phone has Bluetooth capability, ensure that the Bluetooth capability is switched to hidden or invisible mode unless you specifically need it to be visible. This will help prevent other Bluetooth-enabled devices from finding your phone (unless you grant them the necessary permission) and will therefore help protect your phone from worms that spread using the Bluetooth wireless technology.
  
  
• As one avoids downloading attachments received from strangers on the PC. Likewise one should be very careful about opening unsolicited files and text messages on the cell phones. (As in Bluetooth, MMS attachments). Ensure the application or attachment comes from a known source, and is wary of opening files that have unfamiliar text attached to them, even if they come from someone you know.
  
  
• New viruses are created every day, so it’s important to have anti-virus software on your cell phone—if it’s available for your model—and update it regularly.
