How to clean the mining machine

1. No matter what kind of computer, noise is basically a fan problem. If you can't clean up the st on the fan, replace it

2.

1. Back up important data and photos and restore factory settings. Don't install applications from unknown sources. In addition, don't authorize in permission settings

2. You can swipe the computer to see if it can't work. Besides, the computer needs to clean up the memory on time so that it won't get stuck. The memory of the mobile phone is seriously insufficient. It is recommended to clean up the memory lightly, and then restart your mobile phone again

3. Clear the data of the mobile phone. If there are important things, save them on the network disk first, and then restore the factory settings three times. This is safer

< H2 > extended data:

1. Set the security level of the browser. Our common browsers all have the function of security level setting. Through reasonable setting, we can effectively filter the access restrictions of some illegal websites, so as to rece the damage to computers and personal information

2. Firmly resist reactionary, pornographic and violent websites. On the one hand, these bad information will affect the physical and mental health of teenagers, on the other hand, many illegal websites will use browser vulnerabilities to attack users

3. Don't click illegal links at will

When downloading software and materials, we should choose the regular website or official website

5. Turn off some sensitive functions in common communication software. Such as "people nearby" in wechat and "allowing strangers to view photos" in wechat privacy

6. Do not take photos of your family and address. If it goes on like this for a long time, as long as it is analyzed and summarized by others, the information exposed will become a complete set of information, which hides all kinds of unpredictable risks

Do not test related information on the Internet. Some websites do surveys and ask for information about age, hobbies, gender, etc. to do it for a small profit. This information may be used by others, and graally summarized, and sold to others for profit or threat

3. 1. Go to f2pool to register an account. The miner interface has the mining address and miner name
2. Log in the miner (Avalon, roasted cat, ant, miner of different brands and models have different IP addresses. If you find the model, search online), delete the old mine pool in the configuration interface, and fill in the new mining address and miner name
3. Log in to the f2pool miner interface and observe the calculation power. If there is no calculation power, check whether the second step is correct (be sure to delete the previous one, otherwise you are working for others)

4. Try Tencent's computer housekeeper killing. It is the instry's first to apply CPU virtual execution technology to anti-virus software, which will improve the anti-virus ability and efficiency to a certain extent. Eagle eye engine makes housekeeper's anti-virus technology a qualitative leap, improves the in-depth anti-virus ability, and can eradicate the "most persistent virus" on the user's machine without damaging the computer files.

5. Recently, a high load alarm occurred on a server installed with gitlab. CPU usage is as follows:

log in to the server and use top to check CPU usage. This program called minerd consumes a large amount of CPU, as shown in the figure below:

this program is not our normal service program. I think it must be hacked, Then I searched this program. It's really a mining Trojan horse program. Now that I know it's a Trojan horse program, let's see how it works, and then how to repair the back door

this program is placed under / opt / minerd. When it is determined that it is not related to the project, it is judged to be a Trojan horse program, decisively kills the process, and then deletes the minerd file under / opt

In the last month of 2017, bitcoin's nearly crazy rise has made many investors make a lot of money. Many novices who are waiting on the sidelines can only sigh. For many novices who want to enter the instry, the biggest problem is how do I judge whether a virtual coin has investment value

generally, the simpler answer is: if you want to be stable, you should invest in mainstream currencies, such as BTC, ETH, dash, LTC, XRP, and so on. If you want to be small and broad, you should invest in some counterfeit coins or pheasant coins. So the question is again? How to choose so many pheasant coins

the first method is to identify the project itself, including its background, white paper, team, operation, code and ICO release plan

first of all, the most basic question is whether the project is a legal and compliant project. If the project itself is exploiting the loopholes of the law, the project will be forced to stop sooner or later

secondly, the white paper and the team are very important components. The white paper needs to pay attention to the contents and channels of publication. If the white paper can not see the prospects and core competitiveness of the project, it will not have any value. The same is true for the team. If the team members are people without background, it is likely to be a project with money

finally, the operation of the project is related to the release plan of ICO. The operation of the project determines the development route of the project and the integrity of its internal structure, while the release plan of ICO can judge whether the ICO is successful or not

as for the code of the project, it's not necessary for novice Xiao Bai to analyze it, but he also needs to understand it

the second method is a more professional analysis method, mainly through the strategic positioning of the project, market awareness, liquidity, risk and technology

Strategic positioning is to analyze what problems this project is mainly used to solve. For example, bitcoin aims to change global payment, while Ethereum uses blockchain to make various smart contracts

market awareness refers to the brand promotion of the project itself and the attention of users and media, including the information sources of social platforms such as twitter and Facebook

liquidity, the so-called liquidity is to see how much attention each platform attaches to the token of this project. Secondly, the weight of the platform itself is also very important, so you can choose the currency on some larger platforms

risk and technology. Risk naturally refers to the risk of issuance mechanism and inflation. For example, the hard bifurcation of Ethereum is a kind of risk. In terms of technology, it mainly depends on whether there are bugs. At present, bitcoin technology is the most complete. Although it can not support computer language, it is still relatively perfect in cryptography and so on, with few bugs

the third is the commonly used principle of blockchain investment, namely:

1. Does the world really need this

2. What problems did it solve that were not solved originally

Is decentralization really necessary

Does it really have to make its accounts public

Does accounting disclosure really improve its efficiency

To what extent is it closer to a DAC (decentralized autonomous Corporation)

If we decide to invest, what proportion of our capital should we invest

the fourth and most direct choice is to choose the currency according to the exchange

for example, when we want to see a movie, we always choose the movie that is shown in a bigger cinema, because we always think that the movie that can be shown in a bigger cinema should not be too bad. It's the same with currency selection. The currency that can be listed on a big exchange will not be too bad, because a big exchange will consider its own influence while reviewing the currency. No authoritative exchange will go to a junk currency to ruin its reputation

the above four currency selection techniques are for your reference only. Finally, I would like to remind investors that virtual currency itself is a high-risk investment project, and sudden rise and fall is a common thing. I suggest you choose currency carefully, and at the same time, remember not to invest with the heart of sudden wealth, Timely stops are also important

7. Restart the computer, if there is any, just delete the temporary file.

8. Your estimation is that the mining software on disk D is protected, so you can't delete it all the time. You just uninstall it and don't completely delete the installation package and program. It's estimated that the software is installed automatically. Is there anything important on disk D? If not, format the entire disk D once. You can also download the low-level hard disk formatting tool
