Continued Malware warning on a 'fixed' site

I was getting a Malware warning when I went to my site http://speaking tango.com/ I had my friend ‘geek’ fix my site and he wrote a program to update it every hour – because the problem continued. He also addressed the Google verification – so I shouldn’t be getting the Malware warning – but I do.

He just checked today and said that inside the code is okay and the changes are good. He said that there is a vulnerability in WordPress that someone keeps taking advantage of – keeps putting in bad code on my homepage … he doesn’t quite understand it … (and he’s quite adept at IT and familiar with WordPress) – This is not really language I’m familiar with – I just do basic WordPress stuff. I still get a Malware warning as do others. So, at this point … I really don’t know what to do, whether it’s fixed or not fixed etc. Is there anything you can tell me? Help me with this?

Also, after Ignacio Ricci pulled his free Chateau template from my site and your WordPress choices and I didn’t get a reply from him via email, I purchased an updated version of his theme. That’s when the trouble started. So, I replaced it with one of your free themes for now. I don’t know if that has something to do with the problem I’m having now or not. Thanks for any help. If replying – please remember I don’t understand ‘code/html talk’.
