Someone has alerted me that two of my websites have links on random words throughout the copy, now I can't see them from either of my computers, so I thought they might have some malware on their computer but they assure me it is only happening on my sites.

They are hosted through two completely different places and are basic html sites. They are
www.shineweb.com.au/trader/ and
www.advantagetas.com.au

I am stumped, any suggestions?

(and if this post should be in a different location, let me know)
