The latest information on how to prevent the global outbreak of computer blackmail virus.

At present, wana series ransomware has been controlled to a certain extent, but the virus continues to fight and upgrade. You can effectively prevent this WANA ransomware by the following operations. First, temporarily close the port. Windows users can use the firewall to filter personal computers, temporarily close ports 135, 137 and 445 of 3389 remote login (if you don't want to close 3389 remote login, at least turn off the smart card login function), and pay attention to updating security products for defense, so as to minimize the risk of computer attacks.

Second, update the security patches released by Windows in time. When the vulnerability of MS 17-0 10 was just exposed in March, Microsoft had provided security updates for systems such as Win7 and Win 10. After this incident broke out, Microsoft also quickly released special patches for systems that have not yet provided official support, such as Windows XP.

The third is to use the "ransomware immune tool" to repair. Users download the offline version of Tencent Computer Manager's "Ransom Virus Immunity Tool" from other computers, and copy the file to a safe and nontoxic USB flash drive; 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 the "blackmail virus immune tool" to repair the vulnerability with one click through the USB flash drive; By connecting to the Internet, you can use your computer normally.

Fourth, use the "File Recovery Tool" for recovery. Users infected with the virus can use the computer housekeeper-file recovery tool to recover files, and there is a certain probability to recover your files.

In addition, enterprise network administrators can use "Administrator Assistant" to detect the security status of computer equipment. After technical research, the security team of Tencent Anti-virus Lab launched a computer housekeeper "assistant administrator" diagnostic tool for susceptible corporate customers on the evening of 14. As long as the enterprise network administrator downloads this diagnostic tool and inputs the IP or device name of the target computer, he can diagnose whether the target computer is infected with ransomware. Under the guidance of the diagnosis report, unpatched medical equipment can be patched in time to arrange defense.

Note: Windows users should try to avoid visiting high-risk web pages in the near future. At the same time, if they are unfortunately poisoned, don't pay the ransom, contact the security vendor to help recover valuable data, or completely remove the virus by formatting the hard disk.
