This article mainly introduces what is the main way of computer virus transmission, the article is very detailed, has a certain reference value, interested friends must read it!

The main way to spread computer virus is to use the Internet to spread. Computer networking resources sharing has become easier, people often download on the Internet, free sharing software, virus files inevitably among them, which makes the virus spread faster, the Internet is the main way of modern virus transmission.

The transmission of the virus can be roughly divided into two types:

One is the spread of the Internet, including the Internet and local area network, and the other is the spread of mobile media, such as U disk, mobile hard disk and so on.

Mobile media propagation

(1) through floppy disk: by using an externally infected floppy disk.

For example, system disks from different channels, software of unknown origin, game boards and so on are the most common ways of infection. Due to the use of floppy disks with viruses, the machine is infected with the virus and transmitted to uninfected "clean" floppy disks. A large number of floppy disk exchanges, legal or illegal program copies, and the uncontrolled use of all kinds of software on the machine has caused a hotbed of virus infection and spread.

(2) through hard disk: transmission through hard disk is also an important channel, as machines with viruses are moved to other places for use, maintenance, etc., clean floppy disks are transmitted and re-spread.

(3) through the optical disc: because the optical disc has a large capacity and stores a large number of executable files, a large number of viruses may be hidden in the optical disc, and the write operation cannot be carried out on the read-only CD, so the virus on the optical disc cannot be removed. In the process of making illegal pirated software for profit, it is impossible to bear special responsibility for virus protection, and there will never be a truly reliable and feasible technical guarantee to prevent the introduction, transmission, epidemic and spread of the virus. At present, the proliferation of pirated optical discs has brought great convenience to the spread of the virus.

Internet communication

With the popularity of Internet, it adds a new way to the spread of the virus, its development makes the virus may become a disaster, the virus spreads more rapidly, and the task of anti-virus is more arduous. Internet poses two different security threats. One threat comes from downloading files, which may contain viruses. Another threat comes from e-mail. Most Internet mail systems provide the ability to send messages with formatted documents between networks, so infected documents or files may flood into the corporate network through gateways and mail servers. The simplicity and openness of network use make this threat more and more serious.

Download virus files in the network, today, with the increasing popularity of computers, people transmit files and letters to each other through the computer network, which speeds up the spread of the virus, because of the sharing of resources. people often download online, free sharing software, virus files are inevitably sandwiched among them, the Internet is the main way of modern virus transmission.
