Beware: Rogue masquerades as Microsoft Update on Firefox

Rogue software and malware writers are continuing to innovate and customize their social engineering attacks, to make them more believable to users.

Now you have a scareware, presumably from the same team which made another rogue Windows 7 Scanner, that looks like and imitates Microsoft Updates window.

This page is a replica of the real Microsoft Update page which one sees when you access it through the Internet Explorer. However this page comes up when you surf using Firefox.

The real Microsoft Update requires Internet Explorer.

This page urges you to a fake ‘Windows Malicious Software Removal Tool’ Obviously if an unsuspecting user were to click on Install, it would install a rogue antivirus program, reports Sophos.

    Very useful post. But its appalling to see where things are going.

    Thanks for the heads up with this. Just so as that I can warn the folks whose PC’s I look after does this come as a pop-up?

  3. ^ Yes – as far as my understanding goes.

    Thanks Andy.
    I will warn friends and family to watch out for it, though most of them use Opera (as per my suggestion)and only use FF occasionally. IE is only used for Windows updates or for the rare site that only opens correctly with IE.
