Like others, I have used both VirusBarrier and NetBarrier for a number of years. I have had no problems with them. They have both proved superior to other applications I have used. VirusBarrier has caught viruses that both Virex and NAV missed. I no longer even have Norton on my computer and only have Virex because it was free. Unlike another post, I do find NetBarrier a little harder to work with than I would like, but that is in part because it does as much as it does. I would like a list of ports somewhere so I know what I might have to open when I need something obscure to open. Otherwise it is powerful and effective. I recommend both VirusBarrier and NetBarrier to new Mac owners. I don't like the annual upgrade fee for NetBarrier since they don't seem to add much for it. I (and others) seem to review VirusBarrier and NetBarrier at the same time because there is a feeling they do go together. Both are good and I recommend both. I have rarely needed support so I can't comment on that. Years ago I did call them and received good service. That was my only need for a service question. I know Intego messed up a while back with their news releases, but their products are good. Hopefully, they learned from that episode.
