## ❌ NEVER Download:
- Cracked software or keygens
- "Pre-activated" commercial software
- Software claiming to bypass security
- Repositories with suspicious engagement patterns

## ✅ ALWAYS:
- Download from official vendor websites
- Verify digital signatures
- Check repository authenticity
- Use package managers when possible
- Read reviews from trusted sources

# 1. DO NOT EXECUTE any files from the repository

# 2. Disconnect from network (if already executed)
# Windows:
netsh interface set interface "Wi-Fi" disabled

# 3. Run full system scan with legitimate antivirus
# Windows Defender Offline Scan
# Settings > Update & Security > Windows Security > Virus & threat protection
# > Scan options > Microsoft Defender Offline scan

# 4. Delete all downloaded files
rm -rf /path/to/downloaded/malware

# 5. Change all passwords from a clean device

# 6. Monitor for suspicious activity
# - Unusual network traffic
