Threat description
IndoVirus.A creates multiple copies of itself on all available drives. IndoVirus.A attempts to disguise its executable file(s) as Windows folders. It changes the attributes of the original root folders to "hidden" and makes copies of its file using those folder names. It displays a folder-like icon and adjusts the Folder Options/View to "Do not show hidden files and folders" and sets "Hide extensions for known file types". The result of this disguise are multiple files using folder-like icons lying in wait for the computer user to click on them.
