I am disgusted with Norton 360! I've never had a problem with its AV or firewall except for slowing down my machine to a crawl. Besides being a terrible resource hog, the interface is dumbed down so much that there's no visibility to what it's doing, technical support is useless, and its backup is a disaster. I can never tell if a backup has actually been done--I've had backups sit for hours and not do anything--and it has to build "backup sets" before you can even select the set you want to run. I'm usually not this hard on a product but I was a software architect for many, many years and I would have held my head in shame to release a product like this.
