Hahah.
Those detected "Coinminer" are the usual false-positives you can get by scanning any/all Mining app using a virustotal.
Most known AVs won't even tag it as positive (check the name of the AV's with positives in your image).

If you're accustomed to mining, you will know if there's really a red flag (through actual usage/different scan results)
But doktor83's miner wasn't one of those.
It's the indirect descendant of this old thread: SRBMiner Cryptonight AMD GPU Miner V1.9.3 - native algo switching

For the second image:
That's mega.nz (url) that you've scanned.
