I recently purchased Port Explorer and had a bit of a problem over the weekend. While viewing all ports that were established I noticed one in red and it said it was established to Mcafee and it also said it was a shared component. I tried to close it but it would not allow it to be closed. I also have process guard, TDS-3 and wormguard. Yes I am a safty girl My questions are: (1) should I be concerned about that port being established and (2) how do I close it? Thank you all for any help you can give me.
