adb can't remove a file from my Cell phone.

Hello.
My Android is infected with "Luck Try" and the virus file is "Kinguser.apk" but adb can't delete it :

shell@android:/ # rm /system/app/Kinguser.apk
rm failed for /system/app/Kinguser.apk, Read-only file system
255|shell@android:/ #

I'm root but it is read only

Any idea?

Try adding the -f option to the rm command.

Code:

rm -f /system/app/Kinguser.apk

Or, try changing the permissions on the file, then try to delete it.

Code:

chmod a+w  /system/app/Kinguser.apk

then try to delete it.

what does the mount command show. is /system mounted as read-only ?

maybe something like

Code:

mount -o remount,rw /system

?

I did both and when I use "-f" it tell me that "-f" not exist. about "chmod" it is not working.

The next thing I suggest trying is to install something like AVAST Mobile Security or 360 Mobile Security (there are others as well). Install ONLY ONE antivirus on your Android. Put it through it paces. It should remove the virus files.

I'm curious how that apk was written to the system partition...

I removed it handy and factory reset but I see "Lucky Try!" on Android
