I have an extension that got into my Chrome, I don't know when or how but its called Hao123 and advertises itself as a search engine, every time I open Chrome it appears in another tab. I've uninstalled and reinstalled Chrome twice now, and both times it has come back. It doesn't appear in my list of extensions and it's not in my list of Programs and Features to uninstall. I understand sometimes it appears there as 'Wspys' or something, but that isn't there.
Any replies appreciated.
