Before you hit the button to download your favourite Angry Birds Space app on your Android, do ensure that it is not the fake game app which has a Trojan malware. According to web security firm Sophos, "The malicious download is a functional version of Angry Birds Space that gains access to your phone using a Trojan horse called Andr/KongFu-L. The cybercriminals behind the fake game can direct your phone to any website, once you've installed their Trojan," reports Mashable.

Rovio has warned on its blogpost, "As you get ready to pop pigs in zero gravity, watch out for fake versions of Angry Birds Space, and make sure to download safe by getting the official game from Rovio."

"The phony app appears to be a fully-functional version of the popular smartphone game," except that it installs malicious software on Android that takes over one's phone," reports Sophos.

Angry Birds Space has been downloaded 3 million times in the three days following its release on March 22.
