How do you get spyware off your computer?

I have security protection installed on my computer but still a spyware attack from the address of safenavweb.com has infected my computer. It started when I was helping someone do a family tree seach. when I googled a name and saw a site, I clicked on the site and it was the wrong name and address put on that site and it went to a spam fake porn site. Now I keep scanning my computer security protection for virises, but I'm still getting pop ups from Internet Explorer saying spyware and virises have been found and to click yes. When I click yes my security says that was sent from the unsafe address safenav.com and is trying to send me spam and infect my computer with viris and spyware. Does anyone have advice what I can do?
