Protection against the Coinminer malware

What is CoinMiner malware?

Bitcoinminer is a file-based potentially unwanted application that may use a computer's resources to generate bitcoin blocks. During this activity, it consumes a lot of processing power and make the computer slower than usual.

JScoinminer is a web-based detection for a JavaScript cryptocurrency miner that runs in web browsers. The JavaScript coin miner consumes enormous CPU resources, making computer very slow. The JavaScript is loaded in the browser when you visit a webpage hosting the JavaScript. The JavaScript runs as long as you stay on the webpage. As long as the website being visited is injected with the coin mining JavaScript, the website will be blocked by this signature. The computer system is not actually "infected" when this detection triggers.
