Open Mouth and Insert Foot?

This is probably a very dumb question. Are the BBers who are having so much trouble posting on our blog people who use Windows who are burdened with all kinds of anti-virus protection and extra added software like that? Is all of the Norton or McAfee or whatever stuff interfering with blogging on Google? I am aware that my ignorance is showing because I use a Mac but perhaps some of the safety precautions people have taken are just not compatible with this site. Perhaps Google sends stuff that is blocked by your computer and so your attempt at making a posting "transaction" cannot be completed?
