Random device on my network

Question

So for weeks now, my computer has been acting a bit strange. I've done multiple full scans, and even downloaded Malwarebytes. Sometimes, my computer's tabs go completely black. And with all of those full scans, nothing was found. But one time, I did find something called Worm:Win32/Mofksys.R!MTB. My computer removed it, but I'm also worried that it could've made multiple copies, or even backdoors. 

But on top of that, I noticed this random phone on my network called the Lenovo K50a40. And I'm starting to get worried that I may've been hacked.

But I know that I haven't downloaded anything suspicious. I even use AdGuard. Does anyone know about these problems? On top of that, writing this, it disappeared from my network. Does anyone know what to do? I've already put everything on OneDrive and if I have to, should I fully wipe my computer? 

Answer 1

In case there is any malware, you could perform full scan and it will be removed like the picture your posted.

Regarding to the driver, are you able to right click and uninstall it?
