Correct, using the Internet to spread has become the main way for computer viruses to spread. Computer network resource sharing has become easier. People often download and share software online for free, and virus files are inevitably included in them, which makes viruses spread. Speed ​​is accelerating, and the Internet is the main way modern viruses spread.

Has the use of the Internet become the main way for computer viruses to spread?

#The operating environment of this article: Windows 7 system, Dell G3 computer.

There are roughly two ways of virus transmission:

One is through the Internet, including the Internet and LAN, and the other is through mobile media, such as U disks, mobile hard drives, etc.

Mobile media spread

(1) Through floppy disks: By using floppy disks infected by the outside world.

For example, system disks from different sources, software from unknown sources, game disks, etc. are the most common infection routes. Due to the use of virus-containing floppy disks, the machine becomes infected with the virus and is transmitted to uninfected "clean" floppy disks. A large number of floppy disk exchanges, legal or illegal program copies, and the uncontrolled use of various software on the machine have created a hotbed for virus infection and spread.

(2) Through the hard disk: Infection through the hard disk is also an important channel. Because the machine with the virus is moved to other places for use, maintenance, etc., clean floppy disks will be infected and then spread.

(3) Through the CD: Because the CD has a large capacity and stores a large number of executable files, a large number of viruses may hide in the CD. Write operations cannot be performed on read-only CDs, so the Viruses cannot be removed. In the process of producing illegally pirated software for profit, it is impossible to take special responsibility for virus protection, and there will never be truly reliable and feasible technical guarantees to avoid the introduction, infection, epidemic and spread of viruses. Currently, the proliferation of pirated CDs has brought great convenience to the spread of viruses.

Internet spread

With the popularity of the Internet, new ways have been added to the spread of viruses. Its development makes viruses likely to become disasters, and the spread of viruses is even more Quickly, the anti-virus task becomes more difficult. The Internet brings two different security threats. One threat comes from file downloads. These files that are browsed or downloaded may contain viruses. Another threat comes from email. Most Internet mail systems provide the function of transmitting emails with formatted documents between networks. Therefore, documents or files affected by viruses may flow into the corporate network through gateways and mail servers. The ease and openness of using the Internet make this threat increasingly serious.

Download virus files on the Internet. Today, as computers become increasingly popular, people transfer files and letters to each other through computer networks, which accelerates the spread of viruses. Because of the sharing of resources, people often download and share software and viruses online for free. Files are inevitably included, and the Internet is the main way modern viruses spread.
