1. The device that has been infected with the virus is reinstalled. Delete all disks and recreate them
2. In short, blackmail virus is a computer virus that uses Windows system vulnerability to maliciously encrypt user files and then extort money < / UL >

(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
3. 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.
