PUA.Coinminer is a detection for a file based cryptocurrency miner that runs on your system. These miners consumes enormous CPU resources, making computer use sluggish. If you haven't downloaded the file it may be brought onto your system through various sources like bundled in PUA, Exploitation etc. If you find this signature hitting its expected that a miner is hosted on your system.

These attacks are often just javascript code run in your browser. This code only runs while you are on an infected web site, and while the browser session is still active. Norton will intercept this code and block it. When you close the browser, the code is gone. There is nothing downloaded to your computer, which is why all your scans find nothing.
