Spybot Search and Destroy is stand-alone anti spyware. It doesn't interfere with Norton or Malwarebytes because it doesn't run in real time. You run a scan to find spyware. I used to use it too back in the old XP days, but now I use Malwarebytes Pro.
If you redownload Spybot, make sure you don't get the product that includes anti-virus software.
