AVG Internet Security is the paid, mid-tier security suite in AVG's lineup, sitting above the free antivirus edition by adding several extra layers of protection rather than relying solely on Windows' built-in defenses. At its core, the product uses a shared malware detection engine combined with heuristic scanning technology to identify both known threats and newer, zero-day malware through cloud-based file analysis. Beyond basic virus scanning, it includes its own dedicated firewall rather than depending on the operating system's firewall, giving users more direct control over network traffic and blocking attempts. The suite also adds Ransomware Protection to guard specific folders from unauthorized file changes, Webcam Protection to prevent unapproved access to a connected camera, and an Online Shield that blocks malicious links and unsafe websites before they load. A Secure DNS feature works in the background to confirm that a website's address hasn't been redirected to a fraudulent copy, which helps reduce the risk of phishing through DNS-based attacks. For Outlook users, a built-in spam filter helps reduce unwanted or suspicious email traffic reaching the inbox. The software is also designed to run in Passive Mode alongside other security tools without causing conflicts, so it can complement, rather than replace, other protection already installed on a device. Multi-device versions extend this protection to Android smartphones and tablets through a companion mobile antivirus tool, while Mac coverage is offered as a separate, platform-specific edition with its own system requirements. Because AVG Internet Security is typically sold as a licensed subscription rather than a single-device product, it works well for buyers comparing multi-device antivirus options who want firewall-level protection beyond a basic antivirus scanner.
