What is the main transmission medium of computer viruses (what is the main transmission of computer viruses)

Audio commentary

Hello, everyone. The meeting will answer your questions. Computer virus mainly through what media, computer virus mainly through what spread this many people do not know, now let's take a look at it!

Answer:

1. Computer viruses mainly spread through four ways: through the use of externally infected floppy disks, through hard disks, and through optical discs, because the optical discs have large capacity and can store a large number of executable files; through network communication, this method spreads very fast and can spread all over the network in a short time; computer viruses are called viruses because of their infectivity.

2. The main channels are as follows:

3. Through floppy disks: the most common way of infection is to use floppy disks infected from outside, such as system disks from different channels, software of unknown origin, game disks, etc. Because the floppy disk with virus is used, the machine is infected with the virus and transmitted to the uninfected "clean" floppy disk; a large number of floppy disk exchanges, legal or illegal copies of programs, and the uncontrolled use of all kinds of software on the machine, resulting in a hotbed of virus infection and spread.

4. Through the hard disk: transmission through the hard disk is also an important channel, because the machine with the virus is transferred to other places for use and maintenance. Clean floppy disks are transmitted and rediffused

5. Through the CD-ROM: because the CD-ROM has a large capacity and stores a large number of executable files, there may be a large number of viruses hidden in the CD-ROM, and the CD-ROM cannot be written, so the virus on the CD-ROM 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 avoid the introduction, infection, epidemic and spread of the virus. At present, the proliferation of pirated optical discs has brought great convenience to the spread of the virus.

6. Through the network: this infection spreads very fast and can spread to all machines on the network in a short time; with the popularity of the Internet, it adds a new way for the spread of the virus. Its development makes the virus possible to become a disaster, the virus spreads more rapidly, and the anti-virus task is more arduous. The Internet poses two different security threats. One threat comes from file downloads, which may contain viruses. Another threat comes from e-mail. Most Internet mail systems provide the ability to transfer e-mail with formatted documents between networks. As a result, 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.

This is the end of this article. I hope it will be helpful to all of you.
