Referrer Spam from russia

I get hits to my blog on a page I don’t have for a page colum referred by in Moscow. I know other people have had this problem, but I don’t understand how to stop them. From what I’ve gathered that can be a real problem if they do it a lot to your blog. I thought I read something about htaccess, but I haven’t been able to find out how to do anything with it that is understandable. Am I doomed to have to deal with this or is there a plugin in or some alteration with something (with instructions…pleeeease!) I’m not computer illiterate, it’s just that this is something new to me. I tried finding a fix on here, searching Google and also checking Youtube with no luck. Help, please!
