How to be implanted by mining machine Trojan horse

1. This trojan takes advantage of the "eternal blue" vulnerability to attack and spread in the local area network. It builds a robust botnet of the infected machine, supports the self-renewal of the intranet, and lurks in the computer for a long time to extract Monroe money. Because most ordinary personal computers have been patched by windows security update and Tencent computer manager and other security software, they are basically not affected by wanna miner. It is suggested that if the suspected wanna miner mining Trojan horse is found, the poisoned machine can be located and isolated in time. It can be judged by scanning port 26931. If the port is open, the host has been infected; If you need to patch the intranet, all the computers that have not been patched. It is suggested that professional terminal security management software should be installed in the whole network, such as Tencent Yudian. The administrator should carry out mass antivirus and patch installation for the whole network to avoid unnecessary losses.

There are many kinds of mobile phone poisoning, such as relatively easy to kill viruses. You can install anti-virus software to scan and kill viruses. If you can't kill viruses, you can format memory card, hard grid or soft grid. Now let's share the three solutions for mobile phone poisoning< Method 1: anti virus

Step 1: how to deal with mobile phone poisoning? First, connect the data line of mobile phone to the computer, but the computer must be equipped with anti-virus software. If 360 security guard, rising anti-virus software and so on are OK

Step 3: restore the mobile phone to the factory mode, so that the virus in the mobile phone can be removed< First, turn off the mobile phone and press the dialing key, "*" key and "3" key at the same time

Step 2. Turn on the power until the power on interface appears. It must be noted that you can't release any key in this process. Be careful that the hard box will not succeed

Step 3. Wait a few seconds until the word "forming... /" appears, then release the key

Step 4. After a few minutes, the system format is completed, the mobile phone will automatically restart and enter the standby screen, and re-enter the time of the mobile phone.

4. Unfortunately, I'm not a local one, but I'm a professional one. If there is a virus in my mobile phone, you can give priority to some anti-virus software. If there is a phenomenon of mobile phone fee dection after anti-virus, then you have to consider "brush solution", because brush can completely remove all the files in the mobile phone system and re install them, However, pay attention to the selection of the brush package. You should go to a safe and regular website to download it, so as to avoid downloading the brush package that already contains viruses or fee dection plug-ins,

prevention

random code SMS and MMS may contain virus, so delete them immediately after receiving them to avoid virus infection

Do not accept strange requests

when using wireless transmission functions such as Bluetooth and infrared to receive information, you must choose a safe and reliable transmission object. If there is a strange device requesting connection, you'd better not accept it. Because as mentioned earlier, mobile phone viruses will automatically search for wireless devices to spread viruses

3. Ensure the security of download

there are many resources on the Internet that can be downloaded by mobile phones, but some resources are bundled with viruses, which requires users to ensure that the download site is safe and reliable when using mobile phones to download various resources, and try to avoid downloading from personal websites

6. Hello
first of all, it is recommended that you install the genuine anti-virus software, install Jinshan drug bully, and uninstall the trial version of Kaspersky and 360 guard. You can install another Tencent computer manager. This can not only avoid computer poisoning again, but also optimize with Tencent computer to ensure the smooth operation of the computer
at present, since you reformatted the hard disk, it should not be a Trojan horse problem. Because the hard disk format, the computer should be empty, without any corresponding program
after formatting, it is recommended that you install a formal version of the system, just win7 professional version. There is no need to install it as a flagship version
then install Kingsoft and Tencent computer manager. Other security software and optimization software do not need to be installed
any questions are welcome
