A computer virus is software code designed to disrupt computer functions. The creator of a virus also does their best to disguised, mask or hide the virus and to replicate and infect as many computers as possible.
Some viruses are benign, some a nuisance, and some are catastrophic.
Virus protection software helps to prevent the accidental or malicious introduction of a virus to a computer system, and is essential to any computer security system. 170 Phillip Street, Sydney NSW 2000, Australia.
