Microsoft mistakes Skype for a Trojan

A few days after some OneCare subscribers started seeing their access to Skype blocked, Microsoft Malware Protection Center corrects its error.

Users of Microsoft Windows Live OneCare may have found their antivirus protection a little too proactive. Over the weekend, OneCare informed some Skype users that the popular voice-over-IP application was infected with the Trojan Win32/Vundo.gen!D.

Not true, says Skype, which noted that Microsoft has since repaired its overzealous signature file.

On Friday, OneCare subscribers started seeing their access to Skype blocked. Microsoft says it was trying to block a multiple-component family of programs that deliver "out of context" pop-up advertisements, and mistakenly included Skype.

On Tuesday, four days later, it sent out a revised signature file for Win32/Vundo.gen!D that did not include Skype.
