VERY IMPORTANT

JS/Nemucod is a JavaScript downloader trojan that targets users through malware spam campaigns. JS/Nemucod downloads additional malware and executes it without the user’s consent. JS/Nemucod usually arrives on an infected machine through malicious spam emails with .zip extensions. When a user opens the .zip file and double clicks the JavaScript, the default browser (Internet Explorer, Mozilla, etc.) opens and executes JavaScript.
