What are the ways in which computer viruses spread?

Computer viruses spread through various means, often check these transmission channels can be early and effective detection of computer viruses. There are several ways in which computer viruses spread:

1. Through the non-removable computer hardware equipment to spread

That is to say, the use of special integrated circuit chips (ASIC) to spread. This computer virus, although very few but very strong, there is no better detection means to deal with.

2. Through the mobile storage device to spread (including floppy disk, tape, etc.)

The floppy disk is a widely used and frequently moved storage media, and therefore has become a computer virus parasitic "hotbed". Pirated CD-ROM software and games and illegal copy is also the main way to spread the virus.

3. Spread through the computer network

Now through the network has become the first dissemination of computer viruses. In addition to the traditional file-based virus to file downloads, e-mail attachments and other forms of dissemination, the emerging e-mail virus, is completely dependent on the network to spread. There are even computer viruses that utilize network distributed computing technology to divide themselves into parts and hide in different hosts for dissemination.

4. Through peer-to-peer communication systems and wireless communication systems

It can be expected that with the development of technologies such as WAP and the popularity of wireless Internet access, computer viruses spread through this way will also occupy a certain proportion.
