Did you disable the PLUGINS to IE? Here's a link about that.
After years of using Norton products, I stopped a couple of years ago when the software became too buggy and bloated. After purchasing a new computer 2 weeks ago and trying Norton Internet Security for a few days without a problem, I jumped in and bought Norton 360. I immediately had problems closing out of websites using IE. Had to use Task Manager every time. I uninstalled 360, put Internet Security back in,and the problem disappeared.
I hate to give up on 360 already. Anyone have a similar problem or know of a fix?
