Description
Free antivirus usually means a wall of pop-ups, a fan that screams during every scan, and silence the one time ransomware actually shows up. AVG Antivirus Free boils the job down to four switches on one screen: File Shield checks every file that gets opened or written, Behavior Shield watches for programs quietly rewriting the registry or encrypting documents, and Ransomware Protection and Network Inspector each guard their own corner. No digging through settings menus.
It shares its engine and signature database with Avast, so detection is first tier, yet it stays polite on older hardware: a small resident footprint and a monthly Smart Scan by default. The free edition leaves out the firewall and document protection of the paid tiers and shows an upgrade button, but the core protection is complete on its own.
File Shield: Scans every file that is added or opened in real time and blocks malicious content before it runs.
Behavior Shield: Ignores signatures and watches actions: injection, hijacking, mass file changes trigger an alert instantly.
Ransomware Protection: Mark document and photo folders as protected so only whitelisted apps can write to them.
Network Inspector: Checks the current Wi-Fi and router for weak passwords, open ports and hijacked DNS.
Web and Email Shields: Blocks phishing pages and infected attachments before they reach the disk.
Smart Scan: One click checks viruses, outdated software, browser privacy traces and performance issues together, with fixes listed per item.
