An SMS circulating with the message "Is this your photo?" and an attached link is currently circulating.
Clicking the link will download and possibly install an APK called Photoviewer hosted by 6868android.com, which seems to be a variant of the ransomware virus that has become widespread in the US. Delete the SMS immediately if you receive it
