Key Features of Avast Antivirus
Avast Antivirus is known for its blend of powerful features and ease of use. Here’s what makes it one of the most popular antivirus programs available:
1. Real-Time Threat Detection
Avast continuously monitors your system for potential threats using real-time scanning. Its smart AI algorithms can identify and block viruses, ransomware, and malware before they can harm your device.
2. Advanced Ransomware Protection
Ransomware attacks have become one of the biggest threats to personal and business data. Avast provides a dedicated ransomware shield that protects sensitive files, photos, and documents from unauthorized encryption or modification.
3. Web & Email Shield
The internet can be a minefield of malicious websites, phishing links, and email scams. Avast’s Web Shield and Email Shield scan incoming and outgoing data to ensure your browsing and communication remain safe.
4. Smart Scan
With one click, the Smart Scan feature checks for multiple issues — including malware infections, outdated software, unsafe settings, and performance problems — saving you time and ensuring all-around protection.
5. Wi-Fi Security Inspector
Avast checks your Wi-Fi network for vulnerabilities and unauthorized devices. This is especially useful for home users who want to secure their routers and prevent hackers from exploiting their network.
6. Sandbox Mode
This advanced feature lets you open suspicious files in a safe, virtual environment. It’s ideal for testing unknown applications or attachments without risking damage to your actual system.
7. Password Manager
Avast includes a built-in password manager that securely stores and auto-fills your login credentials. It helps you create strong passwords and manage them conveniently across multiple sites.
8. Data Shredder
Simply deleting files doesn’t remove them permanently. Avast’s Data Shredder ensures sensitive information is completely unrecoverable, making it perfect for financial data or personal documents.
9. Behavior Shield
Avast doesn’t just look for known threats — it also monitors software behavior in real-time. If an application acts suspiciously, Avast blocks it immediately before any damage occurs.

Whether you’re gaming, streaming, or working, this mode silences notifications and background scans to let you focus without interruptions.
