I have one of those cheap Chinese AllDayMall A88s tablets.  7 inch.  When it comes on all is fine unless you try to open the browser.  Then things start popping up that are quite unsavory.  So I did a factory reset but it seems all that junk is built in.

Going into settings, apps, I was able to identify and stop a lot of it.  But as soon as I opened the browser it went nuts showing more.  

So I plugged it into my Win7 machine which installed an Alcatel driver for it.  Then I used the Windows version of one-click Kingo root which said it succeeded.  

So I tried to go to the play store to get a good file explorer so I can seek and destroy.  But during the process it wants to log in, so I let it connect to WiFi.  Big mistake.  I never even got to the part of credentials with Google.

So here it is.  Rooted and with the stock file explorer.  I went into the DCIM directory and under Camera there were a bunch of porn photos and a video, which I successfully deleted.

I am not sure how to find the built-in junkware so I can remove it.

Now I am worn out for the night and am hoping someone can give me some advice on how to clean it up well enough that it can be useful.  

The question is in the title:  Now what?
