How to remove the com.android.system.v5?

I want to know that how can I remove that virus(com.android.system.v5) , whenever I turn on mt device (lenove A7600) I see a notification bar which says that youtube has stopped working. It cannot be removed. I tried to stop it from the app manager. I disabled both youtube and the virus file but nothing worked. Help me.

Welcome to Android Central! Why do you think that's a virus? How does that relate to YouTube stopping?

Go to Settings>Apps, select YouTube, then tap Storage, and then Clear Cache/Clear Data. Now see if the YouTube still has problems.
