Multipartite viruses use a combination of techniques including infecting documents, executables and boot sectors to infect computers. Most multipartite viruses first become resident in memory and then infect the boot sector of the hard drive. Once in memory, multipartite viruses may infect the entire system. Removing multipartite viruses requires cleaning both the boot sectors and any infected files. Before you attempt the repair, you must have a clean, write-protected rescue disk.

MP3 files are Moving Picture Experts Group Audio Layer 3 files. They are highly compressed audio tracks, and are very popular on the Internet. MP3 files are not programs, and viruses cannot infect them. This file type has the extension MP3.
Industry:Software
Microsoft developed this operating system for the IBM platform before Windows. Windows operating systems rely heavily on MS-DOS and can execute most MS-DOS commands.
Industry:Software
A memory-resident virus stays in memory after it executes, and it infects other files when certain conditions are met. In contrast, non-memory-resident viruses are active only while an infected application runs.

Master boot-sector viruses infect the master boot sector of hard disks, though they spread through the boot record of floppy disks. The virus stays in memory, waiting for DOS to access a floppy disk. It then infects the boot record on each floppy disk DOS accesses. They are also called master boot-record viruses. Also see: boot record.
Industry:Software
The master boot sector is the first sector of a hard disk. This sector is located at sector 1, head 0, track 0. The sector contains the master boot record. Also see: master boot record.
Industry:Software
The master boot record (MBR) is the 340-byte program located in the master boot sector. This program reads the partition table, determines what partition to boot, and transfers control to the program stored in the first sector of that partition. There is only one master boot record on each physical hard disk. It is also called the partition table. Also see: boot record.
Industry:Software
Mapped drives are network drives assigned local drive letters that are locally accessible. For example, the directory path \\MAIN\JohnDoe\ might be mapped as drive G: on a computer.
