If the computer does not have Internet access, can it be infected with the virus?

OK. USB flash drive Disc propagation.

The general understanding is that there is no [connection] to the Internet....In other words, there is no network cable plugged in...Physically disconnected from the network....

No, as long as there is no virus in the original system. Computers are not food, and they will become moldy if left for a long time.

Yes! USB flash drive spreads! It's possible on mobile devices!

For example, you can use a CD-ROM with a virus, a USB flash drive, a portable hard drive, or something.

If your computer is not on the Internet, you may be infected with viruses because you may use a virus-infected CD, USB drive, or portable hard drive. If your computer does not have access to the Internet, and you do not use a USB flash drive to move a hard disk, this situation is safe.

Duan Tiantian - Beginners These experts have just entered the rivers and lakes, and they have misled others by answering the wrong questions.

The Internet just doesn't have a path with the network, just ask, if the circuit is broken, can you still go?

Some people think that computer viruses are not contagious! Is it true! Let me give you a detailed introduction to whether computer viruses are contagious or not! Hope it helps!

Introduction to whether computer viruses are contagious:

Computer viruses are not only destructive in themselves, but also contagious, and once the virus is replicated or varied, it is difficult to prevent it. Contagiousness is an essential characteristic of the virus. In the biological world, viruses spread from one organism to another through infection.

Under the right conditions, it can multiply in large numbers and cause infected organisms to show illness or even death.

Similarly, computer viruses can spread from infected computers to uninfected computers through various channels, causing infected computers to work malfunctionally or even paralyze in some cases.

Computer Virus Network Infection:

Different from biological viruses, a computer virus is a computer program that is artificially programmed, once this program** enters the computer and can be executed, it will search for other programs or storage media that meet its infection conditions, determine the target, and then insert itself into it to achieve the purpose of self-reproduction.

As long as a computer is infected with a virus, if it is not dealt with in time, the virus will spread rapidly on the machine, and the computer virus can infect other computers through various possible channels, such as floppy disks and computer networks. When you find a virus on a machine, it is often the floppy disk that you used on that computer that is infected with the virus, and other computers connected to the machine may also be infected with the virus.

Whether a program is infectious or not is the most important condition for determining whether a program is a computer virus.

Virus programs achieve the infection and spread of viruses by modifying disk sector information or file contents and embedding themselves in them. The embedded program is called the host program;

Characteristics of computer viruses:

The infectiousness of a computer virus refers to the fact that the virus has the property of copying itself into other programs. A computer virus is a computer program that is artificially programmed, once it enters the computer and is executed, it will search for other programs or storage media that meet its infection conditions, determine the target, and then insert itself into it to achieve the purpose of self-reproduction.

As long as a computer is infected with a virus, if it is not dealt with in time, the virus will spread rapidly on that computer, and a large number of files (usually executable files) in it will be infected. Infected files become a new source of infection, and the virus continues to spread through data exchange with other machines or through network contact.

Normal computer programs generally do not forcibly connect their own ** to other programs. However, the virus can forcibly infect all uninfected programs that meet its conditions for infection. Computer viruses can infect other computers through various possible channels, such as floppy disks and computer networks.

Modified the registry so that the network could not connect!

Go to the next Windows Cleanup Assistant and Sreng and upgrade to the latest version. Then turn off IE to clean up the IE cache, and then disconnect the network (simply turn off the "cat"), and then use the Windows Cleanup Assistant to check and kill all the dishes and operate according to the prompts. After restarting the computer, keep it on and start SRung, click Smart Scan, and check the check digital signature of the process module.

Click Scan, save the SReng report, and send it to the help forum you use to upload the SRng log with a detailed description of your computer's poisoning status. This is more thorough than simply using to kill soft or something.

Based on your description, your host may have won the ARP.

Reinstall the system, format the whole disk, and then ask telecom to change a broadband password for you (** is 10000, free), and then install a firewall, on the line, so the most thorough, the most secure, if there is important information can be copied to the U disk.
