Bitcoin blackmail patch

1. 1, you can install a computer manager on the computer
2, and then open the toolbox, you can see a repair vulnerability
3, using the repair vulnerability, you can automatically detect computer vulnerabilities for repair

2. Open Tencent's computer manager toolbox to fix vulnerabilities, scan and repair them
it is recommended to set the automatic vulnerability repair function. After the function is turned on, the computer manager can automatically repair high-risk vulnerabilities (only including high-risk vulnerabilities, not including other vulnerabilities) at the first time, without user participation, so as to ensure the user's computer security to the greatest extent. It is especially suitable for the elderly, children or primary computer users. The opening method is as follows: enter the computer manager "fix vulnerability" mole - "Settings", and click to open the automatic repair vulnerability.

3. System vulnerability will affect a wide range, including the system itself and its supporting software, network client and server software, network router and security firewall
Tencent computer manager can fix Windows operating system vulnerabilities, and can also intelligently filter out high-risk vulnerability patches and functional patches. Operation method: Tencent computer manager toolbox select "fix vulnerability".

4. In short, blackmail virus is a computer virus that uses Windows system vulnerability to maliciously encrypt user files and then extort money

(3) in view of the current technical means, if blackmail virus can not be solved, it can only be completely formatted, Then, the system is reinstalled and the system vulnerability patch is made to prevent the secondary poisoning

5. no MLM is selling the concept and earning a head fee. The digital currency can be used to trade, it has its own value. There are a lot of people investing in digital currency now, but it is suggested to go to big trading platforms, such as hot money pro, which only has reliable digital currency online, so the risk can be reced.

6. blockchain technology is best known in the financial sector: its origins are integrated with cryptocurrencies that rely on blockchain transparency and unparalleled security to accelerate their success. In essence, through a decentralized distributed digital ledger, the blockchain can record any valuable transaction in the whole computer system, so that no record can be changed quietly without the consensus of the whole computer system
in the financial field, blockchain has been explored and actively used for financial transactions and even contract management. For the supply chain, the benefits are not limited to just keeping accurate records: the blockchain fundamentally reces the time spent on paperwork and authorization. At present, most of the proct or material delivery delays are e to these two points. However, in the blockchain, it does not take time to verify the previous records, only a digital signature is needed to ensure the accuracy and authenticity of digital paper records< At present, consumers have to rely on certificates to verify the authenticity of gemstones. A piece of paper can be easily changed. When many diamond owners value their diamonds with the intention of selling them, they will find that their perfect diamonds are only a little more valuable than glass or smaller diamonds
with the application of blockchain, diamonds can be used as raw stones for unique barcode coding when they are just mined from the vegetable market. While maintaining the integrity of their information, changes made and records handled, they can circulate in the whole supply chain. Throughout the supply chain, authenticity can be verified and there are no unauthorized changes, so the end buyer can track the origin of the diamond (in fact, any other material used to make the final proct) and its entire circulation
similarly, through the blockchain, we can trace the origin, service and ownership history of used cars, so as to rece service fraud (such as the place where the odometer is recalibrated) and the number of stolen vehicles in circulation, and also hope that these instries will be completely terminated
transparency and security
Security and transparency are not usually terms that go hand in hand, but they do on blockchains. As mentioned above, the security of blockchain does not allow any form of unauthorized changes and ensures the authenticity of data. By storing the same "block" information that needs to be collectively approved on its network, the blockchain can not be controlled by any single entity, and there will be no single point of failure, which makes it the most secure platform so far
blockchain can provide transparency, however, its programming mode only allows authorized entities to access information related to their specific interests. For example, buyers may be able to view transaction history, but will be denied access to sensitive or personal information, such as addresses
from a compliance perspective, this helps to ensure that all parties comply with laws, such as the EU's general data protection regulation (gdpr) and South Africa's Personal Information Protection Act (Popi), while still being able to share or access information related to their own parts of the supply chain
there are many application examples of blockchain technology, and supply chain is one of them. However, e to the complexity and number of parties involved in the supply chain, blockchain is considered to be the perfect solution to all the challenges so far, including security, delay and authenticity.

The blackmail virus wannacry is mainly spread by taking advantage of the dangerous vulnerability "eternal blue" leaked by NSA (National Security Agency). Microsoft released ms17-010 vulnerability patch to fix it earlier, but many users did not update the patch in time, so that a large number of computers were attacked by blackmail virus, The least affected system is windows 10, because the latest version of windows 10 1703 has integrated vulnerability patches and is completely immune to blackmail virus. However, it does not mean that win10 is 100% immune to blackmail attack. There are many versions of win10, and the old version will still be infected by virus

Microsoft emphasizes that windows 10 users are not the target of this malware attack. However, according to Microsoft's security announcement, only the latest Windows 10 1703 creators update creator update does not exist the vulnerability of this attack. The previous windows 10 RTM original version, November 1511 update and 1607 anniversary update still need to be patched, If there is no update patch, win10 will still be attacked by blackmail virus, so we must pay attention to update the vulnerability patch in time. Win10 click Start -- settings -- update and security -- windows update to execute system update

8. 1. Don't give money. Even if you hand it in, you may not be able to recover the data

5. If you still can't understand it, cut off the network
[how to prevent bitcoin blackmailer virus] some suggestions on Security:
backup important personal data. Pay attention to personal computer security maintenance, regularly update system patches, safe and reliable antivirus software.

9. 1. Just close port 445
2, and then it's better to fix the vulnerability of virus exploitation
