Lei Jun’s 1992 Paper on a Computer Virus Detection Expert System: Overview and Significance
The article reviews Lei Jun’s early 1992 journal paper on a computer‑virus detection expert system, describing its assembly‑language based methodology, claimed advantages over traditional methods, and the lasting impact of his low‑level programming work on the tech community.
Lei Jun, a well‑known Chinese entrepreneur who graduated from Wuhan University’s Computer Science department in the early 1990s, once authored a technical blog describing his early programming experiences.
In 1992 he published an 8‑page paper titled “Principles and Design of a Computer Virus Determination Expert System” in the journal Computer Research and Development , which proposes an expert‑system approach to virus detection based on assembly‑language analysis.
The paper claims superior accuracy and universality compared with traditional detection methods, and notes that the approach had not been reported in domestic or foreign literature at the time.
Images of the original article and excerpts of the assembly‑language code are widely circulated online, and the work has attracted praise from industry figures such as Huawei’s former vice‑president Li Changzhu.
The article concludes that Lei Jun’s early technical contributions demonstrate his strong programming fundamentals, making him a model for the “old‑generation” developers who had to write highly optimized low‑level code on DOS‑based PCs.
