Avast Features - Antivirus, VPN, Privacy and Cleanup

Security

Threat Protection Features

Six interlocking shields that stop malware, ransomware, phishing, and spyware from every angle.

File Shield

Scans every file as it's opened, downloaded, or modified. Catches malware instantly before it can execute or spread to other files on your system.

Behavior Shield

Monitors all running applications for suspicious behavior patterns. Stops threats that disguise themselves as legitimate software — including zero-day attacks.

Mail Shield

Scans all incoming and outgoing emails and attachments in real time. Detects phishing links and malicious files inside email messages before you open them.

Web Shield

Analyzes every website you visit for malicious scripts, drive-by downloads, and phishing pages. Blocks dangerous URLs before the page even loads.

Ransomware Shield

Creates a protected zone around your most important folders. Any program attempting to encrypt or delete your files is blocked and you're immediately alerted.

AI Scam Assistant

Avast's AI assistant evaluates suspicious text messages, emails, and pop-ups. It explains what's dangerous and why, then helps you take the right action.

Privacy

Privacy & Identity Features

Protect your personal data, browsing habits, and online identity from trackers, hackers, and data brokers.

SecureLine VPN

AES-256 encrypted VPN that hides your IP address and browsing activity. Connect to servers in 34+ countries to bypass geo-restrictions and secure public Wi-Fi.

AntiTrack

Blocks advertising trackers, analytics scripts, and social media buttons from following you across the web. Randomizes your digital fingerprint to prevent profiling.

Webcam Shield

Notifies you whenever an application tries to access your webcam or microphone. Blocks unauthorized access from spyware and malicious software instantly.

Hack Alerts

Monitors thousands of data breach databases for your email address. Sends an immediate alert if your passwords or personal data appear in a known breach.

Identity Protection

Monitors dark web forums and data broker sites for your personal information. Alerts you if your name, address, phone, or financial details are being traded online.

Banking Mode

Launches an isolated, hardened browser session for online banking. Keyloggers, screen recorders, and other spyware cannot see what happens inside Banking Mode.

Performance

Speed & Performance Features

Keep your device running at peak speed while Avast works silently in the background.

Cleanup Premium

Removes junk files, browser cache, temporary data, and unused app leftovers automatically. Frees an average of 235 MB of disk space every single day.

Driver Updater

Scans for outdated or missing device drivers and updates them automatically. Outdated drivers cause crashes, slowdowns, and security vulnerabilities.

Smart Scan

A one-click comprehensive scan that checks for viruses, outdated software, network vulnerabilities, performance issues, and privacy threats all at once.
