More than 17 new gaming apps with trojan found Avast in the Google Play Store. Specifically, apps are part of the HiddenAps family, a trojan that is presented as a secure and useful application and brings content outside of its environment to the user's device. Avast has already identified and reported 47 of these applications that have already been downloaded more than 15 million times. Any device infected with trojan will continue to see the relevant ads, even if they uninstall the relevant app that caused the situation. Logically, users will be much more careful with what they download to their mobile phone.
