When I `cd ~/.Trash` in the terminal, it shows that there is a folder `Downloads`, and inside the `Downloads` folder, another folder `Reactions`, and inside `Reactions`, there is a file called ![virus][1]

Shouting down or restarting the computer does not work to empty the trash. Also, I should say that the file is hidden and is not showing when I open the Trash folder. Is it a virus? If yes, how do I get rid of it?

![virus 2][2]
