(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
Unfortunately, Windows users are attacked by wana series of blackmail virus (bitcoin virus). The current solutions are as follows: (never pay ransom in any case, there is a lot of evidence that even if ransom files are paid, they cannot be decrypted.) < UL >
Windows users can completely eliminate wanacry blackmail virus on devices by formatting all hard disks
indivial users can contact domestic and foreign security manufacturers, such as Qihoo 360, Jinshan drug bully, Kaspersky, mcfel, Tencent security manager and other security centers for assistance in recovering important data
use the file recovery tool to recover. Users who have been infected with the virus can use the computer manager - file recovery tool for file recovery, with a certain probability of recovering your documents
note: we will continue to pay attention to the handling methods of relevant security manufacturers and wait for a more superior perfect unlocking scheme
< H2 > Windows users can install security patches in time, update anti-virus software, and avoid visiting high-risk websites. At present, the wanacry virus has been preliminarily controlled, so users need not panic and fight rationally< br />Windows users can completely eliminate wanacry blackmail virus on devices by formatting all hard disks

use "blackmail virus immune tool" to repair. Users download the offline version of Tencent computer manager "blackmail virus immunity tool" through other computers, and the files to a safe and non-toxic U disk; Then turn on the designated computer when WiFi is turned off, the network cable is unplugged and the network is disconnected, and back up important files as soon as possible; Then use the offline version of "blackmail virus immunity tool" to fix the vulnerability with one click through USB flash disk; Network can be normal use of the computer
use the file recovery tool to recover. Users who have been infected with the virus can use the computer manager - file recovery tool for file recovery, with a certain probability of recovering your documents
note: we will continue to pay attention to the handling methods of relevant security manufacturers, waiting for more superior perfect unlocking.
At present, 360 is the first in China to launch 360 anti extortion service
to provide document restoration and decryption service for the current popular specific Trojan family using asymmetric encryption
download and install the latest security guard 11.0 beta, and click "anti blackmail service" in the main interface
2, and then open the virus check and kill to check and kill the computer virus
3, and then open the toolbox to have a document guardian to decrypt the file
suppose that a supercomputer can violently try 1 billion passwords in one second by setting a password with numbers and uppercase and lowercase letters (a total of 62 characters), then:
it takes 1 second to crack 5-digit passwords (62 ^ 5 = 920 million),
it takes 62 seconds to crack 6-digit passwords,
it takes 1 hour to crack 7-digit passwords,
it takes 2.5 days to crack 8-digit passwords,
it takes half a year to crack 9-digit passwords,
it takes 100000 years to decipher 12 (more than the history of human civilization),
it takes 24.3 billion years to decipher 15 (more than the age of the universe)
the 15 bit password takes a few seconds to input more than the 5-bit password, but the decryption cost is almost impossible
even if the quantum computer can increase the cracking speed by 100 million times, it will only offset 27 bits of the 256 bit private key length of bitcoin (2 ^ 27 = 130 million). Even if extraterrestrials appear and the cracking speed is increased by 100 million times for several times in a row (each time the length of the private key is offset by 27 bits), bitcoin can simply upgrade the length of the private key to 512 bits.
