Problem 5: Delta Keeps Getting Detected by Antivirus

Symptoms

• "Trojan detected" warning
• Windows Defender deletes Delta.exe
• Can't download Delta (blocked)

Solution: Add Exclusions (Safe)

This is normal — all executors trigger antivirus due to injection.

3. Exclusions → Add or Remove Exclusions
4. Add Folder → Select Delta folder (e.g., C:\Delta)
5. Add Process → Add Delta.exe

Third-Party Antivirus

• Avast: Settings → Protection → Core Shields → Configure → Exclusions
• AVG: Settings → Components → Web Shield → Exceptions
• Norton: Settings → Antivirus → Scans and Risks → Exclusions

Safety Note: Delta is safe (clean VirusTotal). See safety analysis.
