Android Samsung S5

Hi Kishore, thanks for the reply.
Slight misunderstanding.
I know how to unlock my phone - but its that fact that I cant remove the AVG banner from across the front of it to see the time when I press the button to light it up.
Banner says:-
" Antivirus Contents Hidden      12 "

My phone is screen locked but when I get a notification and press any button to make it light up
(but leaving it screen locked)    I see a message

"Antivirus Contents Hidden      12"  

How do I remove this banner
