Microsoft and their love of AAC

Thomas tells us about his recent experience :

I wanted to tell to Hardmac regulars how much Windows "hates" iTunes/iPod/iTMS/AAC, and how this can become seriously aggravating :
I use Cubase to make music. Once I have completed a project, I export the downmix in AIFF and convert it to AAC using iTunes. Here's what happen when :
- I send it to someone's Hotmail account : "A virus has been detected in the attached file"
- I send it via MSN messenger: "This file has been blocked because it might present a security risk"
- I try to decompress it after I sent it to a PC : "Windows has blocked access to this file because it might present a security risk"
If I encode the same file in MP3, none of the above problems occurs. So, bug, or Microsoft's will ?

Well, that's an interesting question. But it'S quite obvious that Microsoft has a grudge against the iPod and the iTMS.
