How do viruses get into a computer? 10

You open some or**some anonymous** or unknown** things inside may be in the virus, install 360, when your computer has a patch, it will remind you, you go to install the patch, and then start the computer again OK.

Viruses are attacked by exploiting system vulnerabilities, so it is necessary to patch the system well. Don't go online on those unknown little **, these** viruses are the most, and don't usually order those messy links, don't**messy programs. And be sure to install a good antivirus software.,nod32 is good.,I've been using it.,Basically haven't been hit by a virus after installing it.。

If you don't have an antivirus installed, you won't be able to prevent it, because the virus is now mutating too quickly.

Viruses can be transmitted by e-mail.

Oh, my experience is not on the yellow net After some things are finished, use virus software to check and kill them at any time Keep up to date with antivirus software Pay attention to Microsoft's latest patches Important data is backed up frequently I hope it will help you The most important thing is to be aware When you feel that the computer suddenly becomes stuck The work light is on and off The network is disconnected quickly.

There are many, many ways for computer viruses to invade! How many kinds do you know? I'll take you to find out!

Computer virus invasion method:

(1) The infection rate is fast

In a stand-alone environment, viruses can only be carried from one computer to another through media, while in a network, they can spread rapidly through network communication mechanisms. According to the measurement, under the normal operation of the network, as long as one workstation has a virus, it can infect all hundreds of computers on the network within tens of minutes.

(2) Wide diffusion

Because the virus spreads very quickly in the network, it can not only quickly infect all computers in the local area network, but also spread the virus thousands of miles away in an instant through remote workstations.

(3) The forms of communication are complex and diverse

Computer viruses are generally passed on the network"Workstations"to"Servers"to"Workstations"But now the virus technology has advanced a lot, and the forms of transmission are complex and diverse.

(4) It is difficult to completely remove e.

Computer viruses on a single machine can sometimes be solved by bringing poisonous files. Measures such as low-level formatting of the hard drive can completely remove the virus. As long as one workstation in the network is not cleaned, the entire network can be re-infected by the virus, and even a workstation that has just completed the anti-virus work may be infected by another workstation with viruses on the network.

Therefore, only antivirus workstations cannot solve the harm of viruses to the network.

(5) Destructive

Network viruses will directly affect the work of the network, at least reduce the speed and affect the work efficiency, or collapse the network, destroy the server information, and ruin years of work.

(6) Excitability

The conditions under which a network virus is triggered are diverse, and can be an internal clock, the date and username of the system, or a communication from the network. A virus program can be fired and attacked on a workstation at the request of the virus designer.

(7) Potentiality

Once the network is infected with a virus, even if the virus has been removed, its potential danger is huge. According to statistics, 85% of networks will be reinfected within 30 days after the virus is cleared on the network.

The Nimda virus, for example, searches for file shares on the local network, whether it is a file server or an end client, and once found, installs a hidden file named to each one contained"doc"with"eml"file directory when the user opens it via Word, WordPad, Outlook"doc"with"eml"When documenting, these applications will execute the file, thus infecting the machine, while the virus can also infect the file that is started on the remote server. Emails with Nimda virus do not need you to open the attachment, as long as you read or preview the infected email, it will continue to send the infected email to your friends in the address book.

For example, the computer is your house, and the house has skylights, front doors, and back doors, and some small holes through which viruses can enter.

Viruses can infect your computer through various channels such as web pages, USB flash drives, local area networks, etc.

A lot of channels, if you open a web page and if there is a virus, it will run automatically. The U disk is also almost pulled.

You can install some antivirus software on your computer.

Such as PC Manager or something, and then keep it on.

This prevents viruses from entering your computer.
