virus from 'support@microsoft.com' not blocked?

[Remco Barendse]

I have just received the virus that claims to be from
support at microsoft.com

The weird thing it, it isn't filtered at all.

The attachment:
 All information is in the attached file.
    [ Part 2, Application/OCTET-STREAM (Name: "movie28.pif")  73KB. ]
    [ Cannot display this part. Press "V" then "S" to save in a file. ]

was not blocked alothough .pif is in my blacklisted file list and mcafee
didn't seem to have any problem with it either!!

Anyone else having these problems??
