JS:Cryptonight [Trj]

JS:Cryptonight [Trj] is a detection name that may refer to a specific process that harvests your hardware resources to mine for cryptocurrency like Monero (also known as XMR). While JS:Cryptonight [Trj] is not threatening, it may cause a lot of trouble due to the excessive resources it uses. The process may often consume all available CPU resources, therefore ruining your operating system's performance or applications and games.

If your anti-virus product is reporting a JS:Cryptonight [Trj] problem, then you should look into it immediately. The 'JS' in the name stands for JavaScript, which hints that this detection is linked to websites whose source code contains a hidden JavaScript-based cryptocurrency miner. Whenever you are browsing one of these websites, your CPU will be put under heavy load to mine Monero for the website's operators. You should avoid websites that trigger the JS:Cryptonight [Trj] detection and do not disclose that they are hosting a cryptocurrency miner.
