I am pretty darn mad too. I had to uninstall/reinstall McAfee twice. And now, for some reason, both my routers (an Netgear and a Belkin) DO NOT WORK. Why is this? It has to have something to do with the recent internet access issues.
I will not use McAfee products again.
I did get my router and switches to work but "IT" had reset their IP's and configurations. All the computers except the one running McAfee are back on line. The McAfee computer is at the shop to see what they can do with it won't know til Mon.
