I've seen this several other places, but it's never been quite complete in its description as I see it.

On several occasions, the website I try to access (e. g. BBC.com) redirects to a fake firefox update page. The page has several random urls, so blocking the single url won't work. The page pops up a dialog box to install a fake firefox patch file. I've never downloaded said file. Every time that this redirect happens, without any intervention on my part, my firewall catches and eliminates a Trojan located in C:\Users\myaccount\appdata\local\temp, which has a different name every time. I've tried re-installing firefox, to no avail.

Several scans using windows scanner, malwarebytes, and a few others revealed no virus in my computer.

There was also a second similar fake page, but it only ever appeared once.

I don't know how the data sharing thing works, so I'm pasting it all below me. Win 10, Firefox 47.0.1 How long will it take Mozilla to find and fix the security error? Or at least release a warning about the automatic trojan download?

The best guess is that an advertising network is spreading this "malvertisement".

I don't know whether it's a factor, but you have two versions of Flash installed, 18 and 22. Could you pull the full version numbers to check that they are patched up to date? You can view those on the About Plugins page: type or paste about:plugins in the address bar and press Enter. You can use Find (Ctrl+f) for npswf to skip to the Flash plugins.

Current versions:

Regular release: 22.0.0.192 Extended support release: 18.0.0.360

The fake .exe usually under name of firefox-patch.exe is only a risk to the Windows user if they run said .exe. The Firefox browser does not allow running of .exe thankfully and the downloading alone does not install whatever this .exe could install.

How do you figure Mozilla can get out warnings about this without being seen in a negative way or cause worry as it could just serve to scare users about updates in general. Also this seems to only target Firefox users on Windows and not Linux and Mac OSX since they do not use .exe. There is the snippets option for default about:home but would only target say 10% of users.

Have some discussion at https://support.mozilla.org/en-US/forums/contributors/712056 more later in first page and second page.
