I've got an s7582 on the way and want to root but have some queries. I saw your previous posts in the other s7582 thread and was wondering about your rooting method. Did you root your pre-rooted firmware with kingo or vroot? If so, I think this raises the question as to whether or not it is malware susceptible.
Can you please post your rooting method?
