I had a similar problem this morning. Had to uninstall VirtualBox. After that the freezing went away. I found this info on how to get Emsisoft & VB working together, but I have yet to try it: http://support.emsisoft.com/topic/14363-how-to-use-emsisoft-oa-emsisoft-is-v9-with-virtual-box/ Anyhow, if possible uninstall VirtualBox just to see if it makes a difference. You won't lose any of your VB images.
