5.Use patches to solve system vulnerabilities (such as using the vulnerability patching function of software such as Security Guard 360 and Kingsoft Cleanup Expert).

6.Use other third-party software (such as Security Guard 360) to perform security checks again

1. Disconnect the network cable.

2. Use the latest version of antivirus software to kill viruses.

3. Reinstall the system and patch it if it doesn't work.

4. There is one way, you worship me as a teacher

Reinstall the system.

Then install the restoration elf, and you won't be afraid of it in the future

Directly restored, this is called a yin.

It's pure obscenity, and you can't prevent it. Hehe.

Make a shadow system.

It is also possible to install a restore card.

Or write down the other party's IP, find him, k him.

Antivirus, if it doesn't work, redo the system.

Use the killing soft to kill, and make the system if you can't kill it.

Just install a firewall, and you're good to go.

KIS Kaspersky Firewall is recommended.

Remove the virus .........

Or find a network management to change the machine.

The worst way to install the system.

1.Check that the power cord and the monitor cable are plugged in tightly, and if they are loose, plug them back in.

2.Check if the display is on, and if not, press the power button to turn it on.

3.Check if the computer is in sleep mode, and if so, press the keyboard or mouse to wake up the computer.

1. The refresh rate of the display is too high.

2. The graphics card driver failed. Enter safe mode and reinstall the graphics driver.

3. The computer is infected with a virus. In safe mode, use antivirus software for antivirus operations.

4. The computer parts are not in good contact with the screen. Check that computer parts (display cables, graphics cards, etc.) are securely and reliably plugged into the host interface.

5. The speed of the hardware plus staring studio is too high.

6. When playing games, the graphics card does not support 3D acceleration, which will also cause a black screen.

7. The driver of the graphics card is old.

A computer (also known as a computer) is an electronic computer used for high-speed computing, which has been called "one of the most advanced scientific and technological inventions of the 20th century". The computer is composed of a hardware system and a software system, and has many functions such as numerical calculation, hetan logic calculation, and storage memory. Its application field has expanded from the initial military scientific research application to all fields of society, leading to technological progress on a global scale.

The motherboard is also called the motherboard. It's actually just a circuit board, and it's densely packed with all kinds of circuits. It can be said to be the nervous system of the PC, the CPU, memory, graphics card, sound card, etc. are directly installed on the motherboard, and the hard disk, floppy drive and other components also need to be connected to the motherboard through wiring.
