Do you use a third party DNS like Google DNS, Open DNS, etc service for your internet connection?
I use http://clearclouddns.com/ by SunBelt who is the maker of VIPRE antivirus. Clear Cloud DNS prevents me from accidently going to a site which contains viruses and sends spam.

I use Google DNS. I started using it when I figured out that my ISP's default DNS was too slow and didn't resolve some sites (mostly sites with newly-created records).
