Microsoft AV ID's Skype as a Trojan
While I will admit that Windows Live OneCare has been improving of late, that doesn't mean I would recommend it to my friends.
I might actually note also that this issue is definitely not as bad as when Kaspersky's AV product was labeling Windows Explorer as a virus.
It's a false positive, and though some would consider it amusing, for those affected by it, it can be painful. In this case Microsoft's security products, Microsoft Forefront Client Security, Windows Live OneCare and Windows Live OneCare Safety Scanner were flagging some versions of Skype as malware, namely Trojan:Win32/Vundo.gen!D. In those cases, Skype would no longer run.
Microsoft has already released a fix for their signature file and Skype is no longer being misidentified. While Windows Live OneCare has been raked over the coals for its poor initial performance, it should be noted that plenty - if not all - of other AV products have produced false positives at one time or another.
It's just that it's so fun to pick on Microsoft.
