Conflicting virtual machines?

I brought a new macbook pro, migrated all my flies using timemachine. I am now on snow leopard and this is the response I got.

Message:

To continue the installation, shut down all virtual machines that are running or suspended and close parallels desktop and related applications.

I do not have parellels in the background I even shutdown the computer and it came back with the same response. what should I do?
