We are installing CSA 6.0.1. My question is an easy one that I can't seem to find the answer to. With CSA installed, do you need Windows defender installed as well. CSA does not automatically disable it like other vendor software does (symantec, mcafee). Our Vista machines still have defender running but whenever we try to update the definitions via WSUS, CSA blocks the update because it sees the update as a virus. I am thinkng that we can just disable defender because it is not needed but I can't find it anywhere in Cisco's documentation.
