Use kingroot to see boaltware in uninstall tool.....click it to see its location...verify its location by root explorer....
Install busybox.....
Open terminal emulator and type command

mount -o remount,rw/system
cd system/priv-app
chattr -iaA BCTService.apk
rm BCTService.apk
Thats it...:good:
Note :if it says its read only file then located it by root explorer and click few sec then use delete bottom it will ask to convert to rewrite able then click yes then dont delete simply minimize it and get back to terminal emulator and follow process...

I searched all over internet and didnt find any clue....and I finally found a way so m posting it here ....hope it helps...since this virus randomly downloads apps,opens WiFi and data to download it......ur now finally free.....
