Differences between file macro viruses and traditional viruses

The so-called traditional virus refers to the virus of the boot type and the file type. The writing of this virus requires considerable experience in programming and a deep understanding of the DOS operating system, designing a virus usually takes several days to weeks, but on the contrary, it is easy to write the most popular file macro virus. Skilled people can create a virus in dozens of minutes, several virus variants can be made in one day, so writing viruses in the past is just a patent for hackers, and now you and I have the ability to write a slightly powerful macro virus, I guess Bill Gates, the boss of Microsoft, probably did not think of the extent to which the Microsoft Office presentation he planned was changed to today.

Next we will discuss the features of traditional and file macro viruses.

Traditional viruses

Traditional viruses can be classified into two categories: file-type and boot-type. The so-called file-type virus refers to the virus infection target. COM or. the EXE executable file. When we accidentally execute the virus program, the virus uses this opportunity to infect the executable files around us, or resident in the memory for damage or infection. The boot virus itself is hidden in the boot zone of the hard disk or disk. Therefore, every time the computer is started, the virus will be loaded into the memory from the active sector, therefore, the infection rate of the boot virus can be said to be. As long as any disk that is not protected by write protection is put into the disk drive, it will immediately become infected and become a new infected virus. Another virus is characteristic of both file-type and boot-type viruses, known as the "Compound virus", which can simultaneously infect executable files and disk boot zones, that is to say, the virus can execute the file type or hide in the active sector. When the virus file is executed, it will infect other files and activate sectors, when a computer's Boot Sector contains this virus, it will also infect all files in the hard disk and the inserted disk (if the disk is not write-protected ). In fact, any files or commands executed under DOS after poisoning will pass through virus programs first, so some people often think that computers are always strange recently, at this time, it is very likely that you have been infected with a traditional virus. If you are infected with a virus that is poorly written or has bugs (defects, it is also possible that the machine will often occur.

File macro virus

File macro viruses are a little different from traditional viruses in terms of concept. Most of the infections of traditional viruses are transmitted through disks. Therefore, as long as you stop external disks, most viruses can be blocked, however, the file macro virus is attached to every Word file. Unless you do not read the Word file, any foreign Word file may infect you with the file macro virus.
