c++ - I accidentally created a virus. Just how is this a virus? -

-

so doing experimenting strings, see whether store string in variable , display contents of variable onto screen. apparently, antivirus wasn't happy that.

here code: 

#include <iostream> #include <string> using namespace std;  int main() {     string boy = "hello";     cout << boy << endl;      system("pause");     return 0; }

active software may cause harm computer or data has been detected. detected: trojan.win32.shutdowner.aadw

just how on earth did manage that? first year in computer science , enumerations far we've gotten.

is virus or antivirus being 'paranoid'? or in other words mistaking virus due loophole or another?

p.s. i'm using devc++

it antivirus being paranoid. antivirus programs largely based on byte signatures known virus code (some rely on heuristic analysis of runtime behavior). program compiled binary code happened contain random byte signature antivirus recognized known virus, that's all. not unusual antivirus program report false positives once in awhile, on development machines. can add source/output folder(s) antivirus program's list of exceptions not scan them anymore.

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
