YXH-youtube_player.xpi and YXH-youtube_player.crx are malicious Youtube extensions. Hackers have initiated a malicious web browser extension attack which poses as a Youtube Player. YXH-youtube_player.xpi and YXH-youtube_player.crx affect Mozilla Firefox and Google Chrome and spread via Facebook. This spam campaign becomes a lot worse when infected PC users post links on websites that are using Facebook Comments Box. At least those web-links that lead to fake Youtube websites are non-clickable. The bit.ly link redirects computer users to a website which pretends to be youtube.com. The PC user is then urged via a pop-up screen to click a notification and then install a Youtube HD Player. In fact, a PC user doesn't even need to click a notification, a download of the malicious extension starts automatically. You shouldn't install add-ons from suspicious websites.
