NIS 2009 will not scan

I have norton internet security 2009 and it will not scan. The scan just stays at 0 . but it will live update. I used Malwarebytes and it found 6 and remove them but still have problem. I keep geting a message saying “” Host Process For Windows Stopped working and was closed"“” and sometimes on google when i search it redirects me to a different site and  Then SONAR Pops up and says it Detected Bloodhound something and was removed. but yeah its weird.  I have Windows vista 32 bit version. When I try To cancel the scan it Basically Crashes. and Have been getting blue screen from that.
