⚠️ CRITICAL SECURITY WARNING

This repository is a malicious threat distribution channel, NOT legitimate software.

The project viceofficialtower74/Avast-Premium-Security-Windows-Latest exhibits multiple red flags indicating it is a malware distribution platform:

Threat Indicators

Pirated Software Distribution: Offers "cracked" commercial software with "keygen," "activation," and "pre-activated license keys"
Copyright Violation: Unauthorized distribution of Avast premium software
Star Manipulation: Artificial engagement (68 stars at 5 stars/day) suggesting bot activity
Misleading Content: No actual source code or README, only download links
Trust Exploitation: Impersonates legitimate security software to lower user vigilance

Common Payloads in Such Repositories

Trojans: Remote access tools (RATs) for system control
Infostealers: Credential harvesting malware
Ransomware: Data encryption with ransom demands
Cryptominers: Unauthorized cryptocurrency mining
Botnet Agents: Enrolling systems into DDoS networks

What You Should Do Instead

For Legitimate Avast Software

# Visit official sources ONLY
# Official website: https://www.avast.com/
# Official download: https://www.avast.com/en-us/download-thank-you.php

# NEVER download security software from:
# - Unofficial GitHub repositories
# - File sharing sites
# - Torrent platforms
# - "Free premium" offers

For Open Source Antivirus Alternatives

# ClamAV (legitimate open source antivirus)
git clone https://github.com/Cisco-Talos/clamav.git
cd clamav
mkdir build && cd build
cmake ..
cmake --build .
sudo cmake --build . --target install

# Update virus definitions
sudo freshclam
