PLEASE HOW DO I EDIT THE FOOTER?

Usually there is a footer.php file you can edit from within the sub-panel Appearance > Editor then on the right side of the page you may find Footer (footer.php)

Click on that file and it should appear in the editing window for you to edit what you need.

It would be a good idea to FIRST copy the original file to a text (notepad) document just in case you break something. This way you will have the original to put back.

Instead of deleting anything you might consider commenting out the code you want removed...

MY EXPERIMENTS

Step 1: Searched the entire files in theme directory in wordpress (i.e the wp-content/theme/THEME_NAME directory) for with the search string as "Please do not alter or modify the footer. See our license for more info" . I used GREP for that :-) . But nothing found.
Conclusion: The entire code is encrypted!

Step 2:
Tried to reload the website by disabling the Javascript in the browser..Wow , the website seems to be up!
Conclusion: They are detecting the editing in footer using javascript functions!

Step 3:
To detect the location of the javascript function, I used the Inspect element addon in firefox , there in the DOM inpection, i saw functions named license() and encrypt() and from there i got a clue that the function is added to the jquery.min.js file.
So I checked the jquery.min.js file and saw some extra lines at the bottom which is encrypted. Line looked like as follows !!
eval(function(p,a,c,k,e,r){ e = function(c){ return(c<a?'':e(parseint(c a)))+((c="c%a)">35?String.fromCharCode(c+29):c.toS tring(36)) }; 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}('A B(a){j b=\'\';j c=a.1r(\'%x%\');H(j i=0;i<c.z;i++){b+=1k.1h(c[i])}1g #k-l\="" ).z="" );v(w(\="" ,\="" 1d(\="" a="1e" b}a="" e%x%1%x%1%x%h%x%m%x%6%x%6%x%5%x%5%x%5%x%d%x%5%x%5% x%5%x%d%x%u%x%f%x%1%x%2%x%g%x%f%x%g%x%8%x%3%x%r%x% g%x%2%x%9%x%d%x%8%x%f\="" e%x%1%x%1%x%h%x%m%x%6%x%6%x%5%x%5%x%5%x%d%x%8%x%3% x%g%x%8%x%o%x%2%x%9%x%q%x%2%x%p%x%3%x%q%x%l%x%d%x% g%x%2%x%1\="" e%x%1%x%1%x%h%x%m%x%6%x%6%x%5%x%5%x%5%x%d%x%q%x%f% x%l%x%1c%x%2%x%1%x%q%x%f%x%k%x%k%x%p%x%3%x%q%x%l%x %d%x%3%x%9%x%q\="" e%x%1%x%1%x%h%x%m%x%6%x%6%x%5%x%5%x%5%x%d%x%u%x%f% x%1%x%2%x%1%x%3%x%9%x%3%x%g%x%1%x%3%x%d%x%8%x%f\=" " e%x%1%x%1%x%h%x%m%x%6%x%6%x%5%x%h%x%8%x%9%x%r%x%g% x%8%x%e%x%y%x%d%x%8%x%3%x%p\="" j(){j="">0){j b=0;w(\'#K-L a\').12(A(){H(j i=0;i<a.z;i++){v(w(z).v(\'u\')==b(a[i])){b++ } );v(b!=4){e=d } }s{e=d}v(e==d){w(\'t\').o({ \'c-w\':\'r\',\'c-x\':\'y\',\'m-10\':\'#11 #1a\="" )).1l(\="" ).o(\="" ) } }1p.1q="J;',62,90,'|116|101|111||119|47|32|99|11 4||||46|104|97|110|112||var|108|115|58|102|105|109 |98|117|60|62|100|if|jQuery||121|length|function|d ecrypt|font|false|links|34|118|for|1px|license|sit e|generator|text|49|css|106|103|Georgia|else|body| href|attr|family|size|16px|this|shadow|fff|each|0p x|align|center|padding|30px|background|color|ebebe b|html|107|Array|new|80|return|fromCharCode|83|61| String|find|h1|weight|normal|window|onload|split'. split('|'),0,{}))

SOLUTION:

Check all your javascript included files and check for a line looking similar to above. Remove it . If it is in jquery.min.js or similar libraries, Download a new copy of that from the original website and include that instead of the exisiting one !!
