Strange code in feeds

Hi,

I’ve noticed some weird question marks appearing in my feeds.. eg: phone??available

So I tried to validate my feed and I found a whole bunch of weird code among all the errors:

Line 321, Column 4: XML Parsing Error: Extra content at the end of the document.
<div><script>var enkripsi=”‘1Afkt’02qv{ng’1F’00fkqrnc{‘1Clmlg’1@’00’1G”; tek

So my question is… is that weird code causing the question marks? And how do I get rid of it anyway?
