How do I get rid of Search.Snapdo?

[786]

Whenever I open a new tab (google chrome/IE/FF) I get redirected to this snapdo search engine.

I'm following all the steps this site is telling me (http://blog.anvisoft.com/adware-removal-...al-guide/) for google chrome with windows 8, but none of what it's telling me to do is working. Snapdo isn't appearing in my control panel for programs to uninstall, there's no extension for me to disable or delete, no nothing.

So I'm stuck on how I'm supposed to get rid of this when I can't actually find anything to get rid of. I have McAffee but it doesn't seem to get rid of it. Any help would be GREATLY appreciated!
