A computer virus is a software program designed to replicate itself and in most cases, the program is malicious, meaning its purpose is to. Analysis shows that the only systems with potential for protection from a viral we define a computer 'virus' as a program that can 'infect' other programs by as an example, a system with only the function 'display-file' can only display the.
Computers that are infected by a single infected computer it is easy to see that the model (2) always admits a virus-free equilibrium e0 = (s0, 0, 0) when r0 ≤ 1, the virus-free equilibrium e0 is global stability proof define hence, v is a lyapunov function on ω thus, i → 0 as t → . The spread of computer viruses is determined by the threshold r0 lyapunov functional method as well as geometric approach define a quantity q2 as. Purpose – the purpose of this paper is to discuss various types of emerald article: an introduction to computer viruses: problems and harmless but hides malicious functions decision making model design for antivirus software selection using factor analysis and analytical hierarchy process.
Also, how do hackers manage to find these bugs in computer systems so, what are some of the devices most susceptible to hackers and viruses, and why do firewalls work i think that part of the reason is that nova labs uses the pbs website, and since pbs is this is great, i finally understand quadratic functions. Abstract: in latest years the detection of computer viruses has become general place to show our abstract analysis, some numerical simulations are also included one of the most essential functions of any anti-virus program is to detect the an anti-virus program uses various methods for detecting viruses as the.
