HP pavilion dv6-1308sl whitelist

[c0d3]

Hi! I read this guide and i tried to do it. The guide say to change the jnz jump after "test al,al" in to unconditional jump, i haven't found this test but i found a similar situation with ax register. I opened it whit IDA Pro and this is a screenshot of situation: Image1.
Then i edited it and I obtained this: Image2.

is that right? or i need to do more change?

Sorry for my bad english.
