virus detection trojan mono.dll W32/Obfuscated.M 2011-04-08 15:25:56 while installing

Hi,

During running the installation of Unity Norman detected a trojan, at least identified the mono.dll as such, twice and put it in quarantaine. Is it a matter of switching off the anti-virus program Norman NVC, because it are necessary files? Or is it really a trojan? I pose the question on the NVC site as well. I will give back their info here.

It's a false positive warning - mono is the open source version of .NET, and is very necessary for unity to run
