HERE WE GO AGAIN, another version of the Windows Security Alert malware.  In a previous article (The Fake Virus Alert) I talked about this malware and how to get rid of it.  Unlike the version I talked about in the article, this version of the pesky malware presented itself in a browser -- Firefox to be exact. It totally hijacked the browser as I couldn't navigate away from that page or close the browser.  The only way I was able to stop it is be killing the Firefox session.  To be fair to Firefox, a couple of my clients experienced this issue using Internet Explorer 8.
