Hacktool.rootkit and Trojan.zeroaccess issues

I just started getting the Hacktool.rootkit and Trojan.zeroaccess threats showing up in Norton. They are also causing random windows to open in IE. I’ve read the threads and it looks like specialized help is needed. I’m unable to remove them on my own. Any help would be appreciated because I’m at the point where I feel like the computer is lost. Thanks!
