Microsoft Security Essentials Mis-identifes Chrome

Microsoft's Security Essentials falsely reports Google Chrome as being a password stealing trojan.  Google talks about the problem here, as well as Microsoft commenting on it here.  The trojan that Chrome is being flagged as is the Win32/Zbot password stealing trojan.  The definition number that has presented the issue is version 1.113.631.0, with users reporting that previous versions did not trigger on Chrome. 

More to come.....

Microsoft has already issued an update for MSE - 1.113.681.0 that did not trigger when I launched Chrome. Coincidentally, Chrome updated itself during this session also.
