It is not infected. Rooting software typically contains methods to bypass security so you may get a false positive.
Here's the direct download link: http://www.kingoapp.com/android-root/download.htm
For rooting, make sure that you have enabled "USB debugging" in your tablet's Settings -> Developer options
Connect to a USB 2.0 port if possible and not a USB 3.0 port.
Swipe down from top of the tablet's screen to see notifications.
The bottom line notification will probably be 'Connect as ...'
Click that line and make sure that 'USB large storage' is checked (not MTP or PTP)
Swipe down again from the top line notification may say 'USB connected'
Click that line and click 'Turn on USB storage'
After it is "really" connected, try the Kingo Root software again.
If "ROOT" or "ROOT AGAIN" works, then you're done.
If not, disconnect the USB cable and reconnect a few seconds later. Try again.
I have found that I must turn on "USB Storage", then it's rooting really successful
So correct procedure is:
- turn USB debugging ON
- select "USB large storage" in "USB computer connection" pop-up
- >> activate USB storage in "USB connected" pop-up << (this was missing in my previous attempt)
After that, rooting is succesfull!
I have removed over 20 applications and now I have 13862 score in AntutuX. In older fw was around 11000.
There is also possible to overclock CPU from default 1200Mhz up to 1450Mhz. For me, 1350Mhz is max. stable.
So I can finally recommend this tablet, it's great ☺
Now it would be great to figure out how to enable CWM...
