Two beginners build F4us, a hobby antivirus project written in C

Two beginner programmers have shared F4us, an early-stage hobby antivirus project written in the C programming language, on DEV Community. The project includes a basic honeypot script to log suspicious access, a simple entropy function to analyze file structures, and a background daemon loop for file monitoring. The developers built it primarily to understand how fundamental security concepts work at a low level. The project is openly available on GitHub but is described as buggy and far from production-ready. The authors strongly advise running it only inside a virtual machine, warning that using it on a real system could cause a blue screen of death or kernel panic.
