My self-written exe file is declared as a virus

Question

I have written a program in Go to create PDFs and zip files with LaTeX and operating system board tools (it has to work on Linux and Windows). A few days ago, Windows Defender classified my exe as a Trojan. Because I share the file with friends: How can I make sure that my program is not flagged as a virus?

The PDFs and zip file are created in an export folder. The following steps are carried out:

• The export folder is emptied.
• An image is tested for a specific size.
• .tex files are copied temporarily.
• LaTex/Docker is started and generates various PDFs using .tex files.
• A zip file is created.
• Temporarily copies are removed
• Some files created by LaTeX are deleted
• Text in the console is displayed in green or red.

I compiled the programm with:

GOOS=windows GOARCH=amd64 go build -o start_myprogramm.exe -ldflags="-s -w" src/,y-programm.go;

My import looks like this:

import (
    "archive/zip"
    "bufio"
    "fmt"
    "image"
    _ "image/jpeg"
    "io"
    "log"
    "os"
    "os/exec"
    "path/filepath"
    "regexp"
    "strings"
    "sync"
    "time"

    "github.com/fatih/color"
)

I have read similar cases. Among other things, it said that you can sign the file. Could this be the solution to the problem?

Answer 1

Without full code, can't determine exact reason.

The reason maybe probably like follows.

• self copy & delete
• regular networking
• create executable files like *.exe or *.dll
• some string patterns
