For orgs which are not ISP's, I just emailed this to nanog.
Hi guys, several ISP's are experiencing a flood of calls from customers
who get failed installations of the recent IE 0day - VML - (vgx.dll).
If you are getting such floods too, this is why.
This is currently discussed on the botnets@ list, as raised by Cox, and I
figured I will float it out here.
No patch is currently available from Microsoft, workarounds are available.
