Therefore, you should always check the location and size of install.wim before deleting it or opening it. The genuine install.wim file should be located in the sources folder of your Windows installation media or recovery partition, and it should be around 3-4 GB in size. If you find an install.wim file in another location or with a different size, you should scan it with Malwarebytes Anti-Malware to make sure that it is not infected.
