A boot sector virus is a computer virus that puts itself in the boot sector of a computer. The boot sector is the partition on the disk drive that contains all of the programs and files necessary for the computer to start up. This ensures that the virus will be executed once the computer is turned on.
Fixing a boot up structure that is corrupted due to a virus can be difficult to deal with depending on the extent of the damage done. Reformatting the hard will can fix the boot up structure. If the virus destroys the Master Boot Record then the hard drive is useless paper weight.
A boot sector virus. Boot sector viruses place themselves in the MBR (master boot record). This is a partition on the hard disk that contains all of the programs and files necessary for the computer to boot up when it is powered on. The virus places itself here and gains control of the computer before the operating system can gain control.
boot sector : virus runs on start up of the computer. program: virus runs when you run a specific program.
A virus that uses both boot-sector and executable functions is a multipartite virus. This type of virus attacks a variety of platforms, and continually re-infects each platform until it is removed.
