Bitdefender Is 2008 Problem

I have this strange problem. After installing Bitdefender Is 2008 on Vista Ultimate SP1 32 bit everything seem to work correctly but under Device manager I have no: profofs.sys and trufos.sys. Device manager is set to show hidden devices. In Event Viewer every time I try to run a scan I get this error:
