Need help removing adware: "Web Protect for Windows"

I goofed not paying attention to a page asking to update java and accepted a bundled load that included something called "Web Protect for Windows". I realized my mistake too late and it's installed in the system. I tried to go into control panel and add/remove program, but when I do, Norton pops up and blocks something called Trojan.Gen.SMH and it doesn't uninstall. If I try to uninstall it again a window comes up that says "Please wait until the current program has finished uninstalling or being changed. <OK>" 

If anyone can help me get this cleaned off my pc, I'd really appreciate it. Thanks!
