Check before installing
- Running it alongside the built-in Microsoft Defender causes conflicts and slowdowns. Keep only one.
- A work PC needs the separate business edition.
What it is
A free personal antivirus from AhnLab. It provides real-time monitoring and malware scanning, and tends to respond quickly to malware common in Korea. Free for personal use only; companies need a separate business product.
When to pick this
For a Korean antivirus on a personal PC. On a work machine, the built-in Defender costs nothing and avoids conflicts.
Details
Real-time monitoring
Scans files as they are opened or downloaded, unlike scan-only tools that run on demand.
Do not run it alongside Defender
Running it at the same time as the built-in Microsoft Defender makes both scan each other’s work and slows the PC. Keep only one antivirus.
Business use
Free for personal use only. Installing it on a work PC creates a licence problem.
