statement cited by ovid:  The ability for the platform to understand programmes in different languages makes the threat from worms and trojans much greater, as many of these are written in other languages such as Perl and currently have no anti-virus products.

echo: It's rather amusing that this statement is in direct contradiction with one of the major features of the .NET architecture: the Common Language Runtime.

My understanding is that there is no known design problem involving CLR with multiple languages. The problem is a that M$ is unwilling to restart from scratch. M$ need indeed to leverage its existing code. So, to use M$ terminology, managed code is allowed to call unmanaged code. As a result, a cleanly designed sandbox is opened to all virii thru this use of unmanaged code. It will take years to transmogrify existing code to "managed code".
