Skype presents no adware risk. It was an error by Microsoft:
“…Microsoft said Wednesday that a buggy antivirus definition update, released Friday, had mislabeled Skype as pop-up adware program called Win32/Vundo.gen!D. The issue was fixed Monday in a signature update so users who have version 1.31.9121.0 of Microsoft’s malware signature file should be fine.”
The problem should be solved with an update:
From information that was provided by several experts at Spywareinfo, the Skype program itself should not have been damaged by this Microsoft error. The update should restore normal Skype functioning.
