- Refers to computer viruses that have a parasitic approach to boot viruses and file viruses
- Refers to a computer virus with a parasitic way of boot virus and file virus, so it is more destructive, has more opportunities for infection, and is more difficult to kill. This virus expands the route of transmission of virus programs. It infects both the disk's boot record and executable files. The virus will be activated when the disk infected with this virus is used to boot the system or call to execute the infected file. Therefore, when detecting and removing a complex virus, it must be completely and thoroughly eradicated. If only one characteristic of the virus is found, it should be removed only as a guided or file virus. Although it seems to be removed, there are still hidden dangers. This disinfected "clean" system is even more aggressive. This virus includes Flip virus, New World virus, One-half virus and so on.
- According to the degree of harm to the host, computer viruses are generally divided into three levels: macro viruses, file infection viruses (also known as application infection viruses), and boot sector viruses. Macro viruses are the least harmful. They usually infect some word processing programs, and they appear to insert illegal characters or phrases in the document. The latter two viruses have a greater degree of harm, and mixed viruses usually combine the characteristics of the latter two viruses. This can both increase the degree of virus harm and enhance the concealment of the virus. File-infected viruses are automatically loaded each time a user executes an executable file. The boot sector virus infects the operating system when the computer starts, and each time it boots, it infects the virus.
Because hybrid viruses are difficult to eradicate. Therefore, security experts recommend that prevention of viral infections should be the main focus. You can refer to the following methods to prevent virus infection: install anti-virus software and keep the virus database updated; do not easily view unknown emails and attachments; avoid downloading programs from unknown websites.
