No Hover Links

What kind of advertising are you using. Many ads (for example adsense) will have styling of there own, the only way to change it is inside the adsense account.

But if it are just text links, your class should work. I saw on your site that there’s no nohover class styled.
The css would be:

.nohover a:hover {
color:#fff;  /*same color as none hover state*/
}
