Hello, I have purchased 5 month ago a chinese Lenovo S850t. So far everything was fine, but after an update i received some problems: programs installed without my permision, slow down. Now Malwarebytes find this trojan here: system/app/GoogleQuickSearchBox.apk (Android / trojan.Sivu). I try to remove it but was not possible because is part of the system. Phone specs: LENOVO S850t DUAL SIM, 3GB RAM 16GB ROM, MTK6592 octa core CPU ANDROID 4.4.2 ROOT - was rooted when i puchase it, now the root is gone. The phone also has factory installed Superuser and neither I can remove and does not work well because it says something about binaries.SECURITY SOFTWARE INSTALLED: Bitdefender Antivirus, CM Antivirus (only Malwarebytes see this trojan). Please tell me if you need more info, or what can i do to remove this trojan. Thank You in advance.
