rstech_teni is in your tablet as a core system app even though it may be no such thing. I believe it was put there by the tablet manufacturer in some contractual agreement with some advertising entity. The Lookout malware scanner may sometimes detect it as malware you should just ignore it and not try to delete it, as it will result in your problem again.
You will not be able restore the tablet from the hardware restore menu (hold power & up vol) because it will not allow you to answer "yes" to the prompt to proceed.

Two ways to fix, (Later, on how to actually select something)
1. (preferred)
Go to >Settings >Apps >All
scroll down to rstech_teni, select it, and then select "Clear data"
If you don't see retech_teni you may find "rs_9104_v30". This may be a clone of rstech_teni, do the same to it.
Your done.

2. (last resort, you will lose installed apps and data)
Go to >Settings >Backup & reset >Factory data reset,
Follow instructions, and your done.

And now the hard part, to deal with the message that will not let you navigate.
The easy way to get to "Settings" is to short tap power button to put tablet to display off/locked.
Then again short tap to turn on screen. You will see the rstecc_teni MSG hit OK in MSG. The MSG should be gone and not come back, do nothing else other than pull down the right upper drop down menu where the settings button is then select settings. At this point the evil MSG will come back.
From here on the frustration will start.
You will need to use two hands. Tap the rstech_teni OK with one finger on one hand and then quickly tap the Apps option with a finger on your other hand. This is kind of time consuming but it works after multiple attempts.
If you have a stylus pen, use it for the second tap to the option you want. It will seriously reduce the time it takes by making the second tap very accurate.
Within a half hour you should be able to get through this.
I know because I had the same problem.

Google your make, model and manual and you should find a .pdf file of the manual that you can download.

Press and hold the power button for about 20 seconds. You should see some flashing. Let go of the button and watch. It should reset it's memory and come back on. If this does not work then call your tablet's customer service.

When you want to watch just keep your hand there, is that a bad thing to you?

Try using a paperclip to reset it on the back, hold it in for 5 seconds, if that doesnt work:
Turn the tablet all the way off, press and hold the VOL - and power at the same time for 8 to 9 seconds, it will show a green android guy with a system recovery menu. Use vol - to go down to Wipe Data/Factory Reset, press the power button to select it, go down to 'yes' to confirm, press the power button to select it, it will wipe the tablet, you then press the power button on 'reboot system'.

do one thing Turn Off Your Tablet
-> Hold Volume Button and Power button for 3 to 5 Secs -> You will see a screen with android and triangle with exclamation mark -> you will also see 4 lines of writing in blue. -> use volume buttons to navigate to 3rd option, use home to select it ( warning this will erase your system data if need please take backup) (memory card is not affected) -> now navigate to 1st option saying " reboot to system" use home key to select it.
I hope this will fix things
