A few days ago I noticed my files were replicating as applications and I deleted them, but then I might have run one of them by mistake and all my games' icons and some apps turned into white blank sheet icons and when I clicked on them a notice appeared saying that I couldn't run them on this PC. I am using a Lenovo e440 with windows 10 pro that I updated from windows 8.1. I have no idea what has infected my pc but windows defender is detecting trojans
