How can a network virus affect a computer?

Hello! Computer viruses are generally spread through ** software and USB flash drive Computer viruses can self-replicate and self-backup without the user's knowledge Fix a series of operations There is also an embedded virus Inject its own executable program into all executable files or other files for destruction This virus is very harmful It will infect many programs and files Usually antivirus software will delete the program together However, most viruses need to be double-clicked by the user to start for the first time Just remember to put ** A single scan of a finished file can greatly reduce the chance of poisoning.

Through USB flash drive, email, QQ, and web pages! Anyway, install anti-virus software, don't open unknown emails and web pages, after the U disk is connected to the computer, the antivirus is opened first! QQ: Don't mess with links sent by others**, or don't accept attachments from people you don't know.

There are two main ways in which the virus can be transmitted:

One is network propagation, including the Internet and local area network, and the other is mobile media propagation, such as U disk and mobile hard disk.

Wait. The details are as follows:

1) Hard disk spread: Because the hard disk with the virus is used locally or moved to other places, maintenance, etc., it is infected by the virus and spreads.

2) Disc disc: Most of the software is burned on the CD, due to the fact that ordinary users buy less genuine software, some illegal businessmen put the software on the CD, and burn the virus files on it in the process of copying.

3) U disk spread: U disk is easy to carry, in order to facilitate the transfer of files between computers, Tu Weixun often uses U disk, which spreads the virus of one computer to another.

4) Virus files on the network, in today's increasingly popular computer, people pass files and letters to each other through the computer network, so that the virus spreads faster, because of the sharing of resources, people often go online, free shareware, virus files are inevitably entrained, and the network is also the main way of modern virus transmission.

There are many ways to spread: it can be transmitted remotely through mobile disks, web pages, emails, and system vulnerabilities, and sometimes hackers will disguise themselves as photos, compressed packages, etc., to spread viruses or Trojans, and deceive users to click and talk about guessing friends.

The main way is still **bad**", "some hacking software in Chatong", (in the case of a vulnerability in your system, hackers can inject viruses through the port, and it is profitable to lose the mountain).

It was found that the personal computer was infected with a virus, and the purpose of disconnecting the network was to prevent the data of the stove file in the computer from being leaked while preventing the computer from being further damagedComputer virusesThe information obtained after the intrusion is generally transmitted to the attacker through the network, and when the computer is found to be infected by a virus, the computer should be disconnected from the network and turned on as soon as possibleAnti-virus softwarePerform a network disconnection scan if you confirm that the virus has been cleared before connecting to the network.

If you find that your personal computer is infected with a virus, in addition to disconnecting from the network, you should also open the antivirus software to scan and kill the entire disk. For ordinary viruses, the general scanning and anti-virus can restore the system state, if the virus is tricky, causing the system to freeze, run slowly, or even the anti-virus software does not work, then you need to restart the operating system.

Once you are done cleaning up the virus, export your important files for backup. Generally speaking, viruses reside in the system partition and reinstall the operating system is the most complete way to get rid of it.

It is found that the personal computer is infected with a virus, and the purpose of disconnecting from the network is to worry that the data will be leaked by the early life and the computer will be damaged.

Computer virus. It is to infect other programs by modifying them and destroying computer resources. Computer viruses are not naturally occurring, they are artificially formed, and the purpose of disconnecting from the network is to prevent others from destroying data.

According to Article 28 of the Regulations of the People's Republic of China on the Security Protection of Computer Information Systems: computer viruses.

Refers to the programming of or in a computer.

A set of computer instructions or programs that destroy or destroy data, affect the use of the computer, and are capable of self-replication.

The damage of computer virus to computing function can be solved by one-click restore function, but the damage to data by computer virus, or the theft of computer virus, will cause greater losses to users. When a user finds that a personal computer is infected with a virus, the first thing to do is to disconnect from the network, and directly unplug the network cable.

Anti-virus softwareGenerally, intrusion attacks can be detected and defended by collecting and analyzing information at several key points in a computer network or computer system. When using a personal computer, users should not open unfamiliar emails casually, regularly upgrade the anti-virus software, and scan the computer for viruses.
