Android Central Question

Hi everyone!
I have installed recently a new system on HOMTOM HT7, and since then the option of adding new people doesn't work.
After that, I have installed several internal apps for adding people, which don't solve that problem.
for example the app Contacts.
Now I see this error while trying to add new people:

java.lang.illegalArugmentExcption:
Unknown authority com.android.contacts

Very important thing!!!!
The phone HOMTOM HT7 was infected with a virus, which forced to delete the original system and to install a new one.
So I think that the file, which is responsible for adding new people, was also infected.

Therefore, I'm trying to search this java file on the internet but I'm not finding it.

Needs your help to fix it.
Thanks!!
