Privacy Protection password

I changed simmcards on my tablet, ans after the SINN PIN it asks me for a Privacy Protection password. It also sent a Chinese message to my Cell:
我的手机可能被盗,请保留发送此短信的号码。
which Google Translate says is “My phone may be stolen, please keep sending this message number.”
My Avast account confirms that Anti-Theft is installed, but NOT enabled on the Tablet.

How do I obtain this password or by-pass this screen?

Looks as if you have Avast Anti-theft for Android:
