# 3). Multipartite Virus

These are both viruses, file viruses, and boot sector viruses. Such viruses spread through different types of media. After embedded in the system memory, these viruses make their way onto the hard drive and in the end infect the boot sector.

These viruses spread to executable files for the boot sector and infect the whole system. This type of computer virus was responsible for many systems crashes in the past due to its dual characteristics, i.e. file viruses and boot sector viruses.
