Question regarding an article from Microsft Hellas's CEO

[Giannis Stoilis]

Hello,
I am the Secretary of the Hellenic Linux Users Group(http://www.hellug.gr/)
In an interview given by "Microsoft Hellas 
S.A."(http://www.microsoft.com/hellas/) CEO(Mr. Christos Tsagkos) at the 
Hellenic Financial Newspaper Naftemporiki(E-WORKING Manazine, Page 4, 
Answer to the 4th question - http://www.naftemporiki.gr/[greek only]), 
there was an abstract saying, word by word: "Let me start by saying 
that, according to a recert reasearch by IDC, Windows is the least 
vulnerable operating system, regarding security issues. The research 
indicates that there are more than twice number of viruses for Linux 
than for Windows". I have searched every recent research from IDC but I 
haven't found that information.
What do you advise us to do? We have already contacted IDC and waiting 
for a response.

Thank you in advance
Regards
- Giannis Stoilis
