However, only a fraction of users with some security consciousness take security measures to protect computers on their own initiative, and others who know the current situation through social networks usually follow suit. This phenomenon is referred to as conformity psychology. It is obvious that more users will take countermeasures to prevent computers from being infected if the malware spreads to a certain extent. This paper proposes a deterministic nonlinear SEIQR propagation model to investigate the impact of conformity psychology on malware propagation. Both the local and global stabilities of malware-free equilibrium are proven while the existence and local stability of endemic equilibrium is proven by using the central manifold theory. Additionally, some numerical examples and simulation experiments based on two network datasets are performed to verify the theoretical analysis results. Finally, the sensitivity analysis of system parameters is carried out.<\/jats:p>","DOI":"10.3390\/axioms11110632","type":"journal-article","created":{"date-parts":[[2022,11,10]],"date-time":"2022-11-10T21:33:02Z","timestamp":1668115982000},"page":"632","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["A Malware Propagation Model Considering Conformity Psychology in Social Networks"],"prefix":"10.3390","volume":"11","author":[{"given":"Qingyi","family":"Zhu","sequence":"first","affiliation":[{"name":"School of Cyber Security and Information Law, Chongqing University of Posts and Telecommunications, Chongqing 400065, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuhang","family":"Liu","sequence":"additional","affiliation":[{"name":"Chongqing Key Laboratory of Computer Network and Communications Technology, Chongqing University of Posts and Telecommunications, Chongqing 400065, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuhang","family":"Luo","sequence":"additional","affiliation":[{"name":"Chongqing Key Laboratory of Computer Network and Communications Technology, Chongqing University of Posts and Telecommunications, Chongqing 400065, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kefei","family":"Cheng","sequence":"additional","affiliation":[{"name":"Chongqing Key Laboratory of Computer Network and Communications Technology, Chongqing University of Posts and Telecommunications, Chongqing 400065, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"280","DOI":"10.1016\/j.icte.2020.04.005","article-title":"A survey of IoT malware and detection methods based on static features","volume":"6","author":"Ngo","year":"2020","journal-title":"ICT Express"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"101895","DOI":"10.1016\/j.cose.2020.101895","article-title":"Multiclass malware classification via first- and second-order texture statistics","volume":"97","author":"Verma","year":"2020","journal-title":"Comput.
