The virus was developed by a Chinese advertising company, Yingmob, and infected over 10M Android devices worldwide.

The malware has root access to your smartphone, so the hackers can do whatever they want, such as spying on your personal information to stealing your bank details.

What can you do about HummingBad?

Install ZoneAlarm® Mobile Securitythat will detect if your phone was infected by the HummingBad malware.

How you should remove it depends on how you were infected. If you installed a Yingmob app and agreed to update the software – you can simply re-set your phone and start from scratch.

To make sure that it was completely removed, do a factory reset, then change your Google password from a PC, so it will ask for new credential when you log in through your smartphone. Be careful about installing apps that are from trusted stores.

But if the HummingBad got root access to your smartphone, a factory reset won’t be enough. You must contact your mobile operator and ask them to flash a new ROM on your phone.
