NIS 2010 doesn't filter spam AT ALL

The spam filter is garbage, it adds senders to a “blocked list” that it doesn’t block and obvious spam like viagra and prescription drugs, bleep enlargement pills, etc come through as well… I get the same senders all the time, about to just return to my outlook built in “blocked list” but I have to copy it from my other computer as this is fresh install of windows 7… both are outlook 2007, any ideas…  no old versions here so this should be working… the only thread I saw seemed to be locked out for additional comments and didn’t address my specific issue anyways, they were saying addresses never got added, mine are there, building quite a list I might add but it doesn’t block anything…  HELP
