Incomplete ActiveX list

I find it strange that 3 out of 5 not known ActiveX
controls are issued by Microsoft.
This is a beta, but i hope that the final version will
contain a more complete list so that unskilled users dont
get insecure about the findings..

Ive sent em all in for analysis so lets see how they turn
out :-)
