Android smartphone users have been issued an urgent warning about downloading apps which could contain invasive malware, with thousands already presumed to be at risk of an attack.
SharkBot, which can steal login and banking credentials, has returned to the Google Play Store, after cyber criminals have dodged intense security measures - with apps only becoming infected with the bug once downloaded and installed.
The virus, which initially surfaced in March earlier this year, has made its way onto two applications which Android users are being urged to delete immediately for their own safety.
