This work aims to develop a series of epidemic models for computer viruses utilizing the Katugampola fractional derivative. This study aims to resolve the time-fractional computer virus propagation model using a hybrid approach that integrates the residual power series method with the generalized Laplace transform. In addition, an example demonstrates the fractional order α and the parameter ρ influence the dynamic behavior of the computer virus propagation model.Computer ScienceEngineeringArticleSCOPUS10.24507/icicel.20.04.4112-s2.0-105032790146
