Check if a file has a certain string in its name C++ - c++

Question

I'm programming a tool in C++ to remove the 000.exe malware. The malware creates a lot of files on the desktop named "UR NEXT UR NEXT UR NEXT" etc. My first step is to remove all these files from the desktop. What can I do to check every file on the desktop and for each one that contains the string "UR NEXT" somewhere in the file name, delete it. I have a basic structure of my program already written but I'm really stuck figuring out the user's username folder, then deleting ever file containing "UR NEXT" on the desktop. Any help would be greatly appreciated. I'm using Visual Studio 2019 and I already have an elevation added to the program.
#include <iostream>
#include <Windows.h>
#include <WinUser.h>
using namespace std;
int main()
{
string answer;
cout << "=~=~=~=~=~=~=~=~=~=~=~=~=~=\n000.exe Removal Tool\n\nby OrcaTech\n\nThis tool can be used to remove the 000.exe malware from your Windows PC. Type \"y\" below and press [ENTER] to begin the removal process.\n=~=~=~=~=~=~=~=~=~=~=~=~=~=" << endl;
cin >> answer;
if (answer == "y")
{
cout << "Starting Removal Process..." << endl;
cout << "Your computer will restart multiple times." << endl;
//Stop "run away" spam message boxes
system("taskkill /f /im runaway.exe");
//Change the wallpaper back to the default.
const wchar_t* path = L"%SystemRoot%\\Web\\Wallpaper\\Windows\\img0.jpg";
SystemParametersInfoW(SPI_SETDESKWALLPAPER, 0, (void*)path, SPIF_UPDATEINIFILE);
/* code to delete all files on desktop containing UR NEXT goes here */
system("pause");
return 0;
} else {
exit(0);
}
}

You can use std::filesystem::directory_iterator to iterate over every file in the desktop folder and remove the files with specific names:
#include <filesystem>
#include <string>
#include <vector>
int main()
{
std::vector<std::filesystem::path> filesToRemove;
for (const auto& i : std::filesystem::directory_iterator("path_to_desktop"))
{
std::string fileName = i.path().filename().string();
if (fileName.find("UR NEXT") != std::string::npos)
{
filesToRemove.emplace_back(i);
}
}
for (const auto& i : filesToRemove)
{
std::filesystem::remove(i);
}
}
