TrendMicroTitanium 6 does not comply with policy

Hello,
I have this message when I am trying to connect to work from home. I have the same antivirus on both PCs – Avast AV5. On my home PC I have this error and I cannot skip this. Any idea about this error ? How can this be solved ?
Thank you experts !
