What is a Computer Virus?
A computer virus is a type of malicious software program (“malware“) that, when executed, replicates itself by modifying other computer programs and inserting its code. When this replication succeeds, the affected areas are then said to be “infected“. Viruses can spread to other computers and files when the software or documents they are attached to are transferred from one computer to another using a network, a disk, file-sharing methods, or through infected email attachments.
