I'm guessing you've got eval(base64 code somewhere in your php files, it usually happens from a poorly secured mod that you've uploaded or already infected php files, you need to search your files on your server for that, usually at the top or the bottom of the file, you need to remove that line on EVERY file thats infected and find the file thats either pre-infected or has the code for replicating it.

Think hard what you did recently or uploaded to your server recently.

Of course you could just have some white space at the beginning of your last edited php file

Google says both your sites are safe!
