I completely understand about FB and know that *I* am the Product, I have maybe 1-2 ‘spyware’ hits each month. My Firewall and timed data cleanses both do a good job.
I can’t remember the last time I had a pop-up or anything of that nature.
Thats the ...beauty of Facebook. Your/anyone’s presence there and interactions there gives them datamining that traditional spyware could only dream of. If you are aware of it, it’s all good.
