The Singapore Computer Emergency Response Team (SingCERT) on Monday released an alert to Android mobile phone users of an SMS virus circulating here. SingCERT said the message reads "Is this your photo?" followed by a shortlink. Clicking the link downloads a mobile app called Photoview which is the malware. Affected users are advised to delete the message and uninstall the app and delete the Android Application Package (APK) file from the Downloads folder, which is accessable from the browser's settings page.
