A pc virus is a kind of malicious software program program (“malware”) that, when executed, replicates by inserting copies of itself (probably modified) into different pc packages, knowledge recordsdata, or the boot sector of the arduous drive. When this replication succeeds, the affected areas are then stated to be “contaminated”.
Viruses could cause in depth harm to knowledge and pc methods. They’ll delete or corrupt recordsdata, alter or destroy knowledge, and even take management of a pc system.
