Can't remove virus with Sophos Mobie Security on Huawei Y300-0100 smathphone

Question

Hello, this is my first time to ask a question in Sophos community, I have just become a member. 
 Anyway here is my problem, I have just installed the free Sophos mobile security, I scanned my phone which is a Huawei y300-0100 and it found the following threats Andr/Ztorg-C, Andr/Generic-S, Andr/FkDbgrd-B. 
 They have infected the following apps apps engriks, measure, mobieOcr, skypoll and SysTask, everytime I turn on wi-fi or "Data enabled" I get popup messages that this app or that app has closed . 
 I tried to uninstall it (in Sophos security) but that option is disabled and I don't see anywhere where I am offered an option to choose remove, like in other antivirus (on PC). 
 If anybody has an idea or a solution I sure could you use it. 
 Thank you

Hello, 
 
if looks like the threat is nested in a system app that is in the ROM of your device. This could only have been put there by either the device vendor, the carrier or a 3rd party that had possession of the device before shipping it to you. 
Due to the architecture of Android the system apps cannot be removed unless the device is rooted. That is why Sophos Mobile Security cannot delete the apps.
