编译代码时，防病毒软件说它是病毒并将其删除

嗨，我试着用c++写代码。此代码仅使文本文件易于加密并保存到新文件中。当我编译这段代码时，反病毒软件说，这是病毒/间谍软件Gen:Variant.Kazy.20825。我不知道为什么是病毒。下面是我的代码:

#include <iostream>
#include <fstream>
#include <string>

using namespace std;
void controlParameters(int argc){  //check if input parameters are ok
    if(argc == 1){
        cout << "Pokud chcete text zasifrovat, spustte program s parametrem: -enc "Nazev_souboru.txt"n";
        cout << "Pokud ho chcete desifrovat, spustte program s parametrem: -dec "Nazev_souboru.txt"n";
    }else if(argc > 3){
        cout << "Moc parametru. Spustte si program bez parametru.n";
    }else if(argc < 3){
        cout << "Chybi jeden parametr. Spustte si program bez parametru.n";
    }else{
        cout << "Vsechno vypada zatim dobren";
    }
}
void encryption(string &file);  //encrypt text file
void decryption(string &file);  //decrypt text file
bool controlFile(string &file); //check if file can be opened
int main(int argc, char **argv){
    controlParameters(argc);
    string file;
    file = argv[2];
    if(controlFile(file)){
    }else{
        cout << "Soubor nesel nacist." << endl;
        return -1;
    }
    cout << "Ukonceno.nZmacknete ENTER pro pokracovani..."<<endl;
    cin.get();
    return 0;
}
bool controlFile(string &file){
    ifstream ifs;
    ifs.open(file);
    if(ifs.is_open()){
        ifs.close();
        return true;
    }else{
        ifs.close();        
        return false;
    }
}
void encryption(string &file){
    ifstream ifs;
    ofstream ofs;
    string line;    
    ifs.open(file);
    ofs.open("encrypt.txt");
    if(ifs.is_open()){
        while(!ifs.eof()){
            getline(ifs,line);
            int a = line.length();
            int i = 0;
            while(i < a){               
                ofs << ((char)(line[i]^100));               
            }
            line.clear();
            ofs << "n";
        }
    }else{
        cout << "Nelze nacist soubor" << endl;
    }
}
void decryption(string &file){
    ifstream ifs;
    ofstream ofs;
    string line;
    ifs.open(file);
    ofs.open("decrypt.txt");
    if(ifs.is_open()){
        while(!ifs.eof()){
            getline(ifs,line);
            int a =line.length();
            int i = 0;
            while(i < a){               
                ofs << ((char)(line[i]^100));               
            }
            line.clear();
            ofs << "n";
        }
    }else{
        cout << "Nelze nacist soubor" << endl;
    }
}
