Microsoft Malware Protection Center: We’ve had reports of a new worm in the wild and that generates increased RDP traffic for our users on port 3389. Although the overall numbers of computers reporting detections are low in comparison to more established malware families, the traffic it generates is noticeable. The worm is detected as Worm:Win32/Morto.A and you can see a detailed description of at http://www.microsoft.com/security/portal/Threat/Encyclopedia/Entry.aspx?Name=Worm%3aWin32%2fMorto.A.

Windows 8: The death of malware? The death of anti-malware?

Published: July 25, 2011 Reading time: 3 min

BetaNews: There is a lot of buzz about a recent set of tests by NSS Labs that show the Smartscreen reputation system in Internet Explorer 9 head and shoulders and most of the rest of the body above the competition in blocking malware on the web. I think the results of the test are even more important than they seem, considering previous reports that Microsoft plans to make Smartscreen a base part of Windows 8.
