What it is
An antivirus from ESTsoft, long used in Korea, providing real-time monitoring and malware scanning. Free for personal use; companies and public institutions need a paid licence.
When to pick this
If you are used to Korean antivirus software and this is a personal PC. Otherwise the built-in Defender is enough, and keeping a single antivirus makes the machine faster.
Details
Real-time monitoring
Scans files as they are opened or downloaded.
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.
