Multi-partite viruses perform which functions?

While they can infect the boot sector, their definition is not solely about infecting multiple disk partitions but rather about using multiple infection vectors, including files.

Multi-partite viruses can infect boot sectors, but their defining characteristic is the combination of this method with other infection types, most commonly file infection.

Infecting numerous workstations is a characteristic more commonly associated with network worms or widespread malware, not the specific definition of a multi-partite virus's infection mechanism within a single system.

Multi-partite viruses are capable of infecting multiple parts of a system, such as both the boot sector (or Master Boot Record) and executable files, making them particularly difficult to eradicate. This dual infection mechanism allows them to persist even if one infection vector is cleaned, as the other can reinfect the system.
