Subject: unsafe assembly message in the sql server log

We started getting messages like this one:

2016-09-08 08:00:54.18 spid91  Unsafe assembly 'microsoft.sqlserver.mpusqlclrwrapper, version=10.0.0.0, culture=neutral, publickeytoken=89845dcd8080cc91, processorarchitecture=msil' loaded into appdomain 215 (mssqlsystemresource.dbo[runtime].285).

in the server log (MS SQL 2008 R2)

I don't know much about assemblies and the message worries me.

My understanding is that assembly usually is a procedure written in CLR language, such as C#, compiled and deployed as native code on SQL Server.

There is no s/w that we build and deploy as such assembly - what could be a reason for the warning message? Are there any steps to further investigate it?
