Meaning of Computer Virus
A computer virus represents a malevolent software program, or malware, that, upon execution, self-replicates by altering existing computer applications and integrating its proprietary code. This nefarious entity functions as an executable program with the capacity to self-propagate, wreaking havoc on files and other software within the host computer. It is worth noting that a computer virus can effortlessly disseminate from one system to another, often leveraging storage media such as flash drives and floppy disks.
