How to see if the computer is being secretly mined

1. Using a closed system or an unpopular system is the simplest and most crude method, which is to some extent fruit powder welfare
to prevent hackers from mining with your machine is just like anti malware. Don't visit messy websites, Download messy software, insert picked up USB flash drives, install anti-virus software (Windows Defender on windows is very good, but it's too strict), check and kill viruses regularly, and check abnormal processes and files regularly. If a program attracts UAC, If you don't understand, try to choose no, and don't believe that "it may be misled by anti-virus software". If possible, you'd better install an isolation machine, shadow system, or create a virtual machine directly with Hyper-V of windows system for daily work
for Android phones, phones before Android 6 are unlikely to win. After all, mobile phone mining also needs good hardware. After Android 6, mobile phones have the management of the authority of each application, as long as they don't go blind root, don't install applications of unknown origin, try to download apps from the official market and rece the unnecessary authority as much as possible (you can also use "refrigerator" and "black domain" to prohibit other apps from running in the background)
for the mobile phones of apple, windows and other operating systems, I think that as long as we don't break the prison blindly and keep the system in the latest version, we can prevent the hooliganism of most apps.

2. It's hard to see if the CPU has ever been mined, because the CPU can hardly cause serious aging and discoloration e to long-term full load work, which is not like a graphics card. When the graphics card is fully loaded for a long time, some resistance and capacitance components near the GPU core on the PCB board will turn yellow and discolor e to long-term high temperature, even the PCB board will also change color
as there are not only GPUs, but also video memory, power supply unit and a large number of chip resistor capacitor components on the graphics card, long-term mining will lead to aging of some components, so the life of this kind of graphics card is worrying. But as long as the CPU heat dissipation has been good, basically do not worry, the vast majority can continue to serve for a long time.

Mining is burning graphics card, the following methods can identify their own graphics card is mine card

1: through the naked eye to identify whether the hardware is mine card, in fact, through other ways can also be measured, for example, you go to the computer to test the overclocking performance of the mine card, to compare with the official data, to test the stability of the power supply of the mine card, It can also be measured whether it is a mine card or not

2: the first point is to see if there are any dirt and oil stains on the mine card. If not, it proves that the seller may have done better treatment, or it is not the mine card. If the mine card is very dirty, nine times out of ten it is the mine card. Then we have to carry out the next operation, that is to open the mine card

3: we should pay attention to whether there is an invoice with warranty. The warranty can be guaranteed at the warranty points all over the country, which is not a mine card

extended information

how to avoid buying mine cards: try to buy new cards at the official flagship store of Taobao Jingdong, and if you want to buy second-hand graphics cards cheaply, you can't guarantee it

if the budget is really limited and you have to buy second-hand graphics cards, you should also try your best to buy them by yourself. Don't believe that Internet cafes or studios or companies go bankrupt. Most of the cards bought through this channel are mine cards. Of course, if the indivial buyer has a large number of graphics cards in his hand, please be careful. This probability is also mine cards. Finally, I hope you can avoid mine card, buy your favorite graphics card, happy game

4. There are several obvious manifestations of mining virus in
1. The computer runs abnormally slowly
2. The computer crashes abnormally / gets stuck
3. Nothing is turned on, but the CPU occupancy rate is very high
4. The network is slow and a large number of network requests appear

5. Take it apart. Look at the st inside. If you have a SSD, you can look at the number of times the SSD is charged.

6. Master Lu does have a mining function. Let's see if it's turned on. Just turn it off

7. 01 close Homegroup
control panel – administrative tools – services – Homegroup listener and Homegroup provider are disabled
02 turn off disk defragmentation and automatic maintenance scheling tasks
select disk c-properties – tools – optimize and defragment drives – optimize – change settings – deselect run as scheled
03 close Windows Defender (as the case may be)
control panel – Windows Defender – settings – implement protection – remove check and administrator – enable Windows Defender – remove check
control panel – administrative tools – Services - Windows Defender service is disabled
04 close windows search
control panel - Administrative Tools - Services - Disable windows search
05 set up the superfetch service
control panel – administrative tools – service – superfetch - Startup type – automatic (delayed startup)
06 clean the windows.old folder

Hello, 3a and AAA are the same

A + + is the best screen, AAA screen is equal to a + screen, quality control is also relatively good screen, no bad points

However, considering the quality, a + + is more cost-effective
