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