With all the recent hype about spammers, bots and malware, I found THIS link "Why You Should Never Search For Free WordPress Themes in Google or Anywhere Else"

The first page that google supplied is numbered and discussed in detail to every link provided. It seems they are all cluttered with malware, so be careful...:)

Thanks for pointing this out. We also found many free themes with hidden back links in them. It is amazing what people will do to try to get a better SE ranking for there sites.

Its a pleasure.:)

I actually found a post here on daniweb yesterday where a user wants to use WordPress and wanted to search for themes. Luckily he got the warning in time.
