Many of my friends, if they find their computers poisoned, will only be panic and complain in the computer. In fact, we should take some urgent measures calmly at this time. Next, let's work with the editor to learn some emergency techniques!
Computer
1. Do not restart.
Generally, when an abnormal process is found, an unknown program is running, or the computer runs slowly, or even IE often asks whether to run certain ActiveX controls or debug scripts. At this time, it indicates that it may have been poisoned. After many people feel poisoned, they think the first thing to do is to restart the computer. In fact, this approach is extremely wrong. When the computer is poisoned and restarted, it is very likely to cause greater losses.
2. Immediately disconnect the network.
After a virus attack, it not only slows down the computer, but also damages the data on the hard disk. It may also send personal information, viruses, and other information to the outside, further expanding the harm. In this regard, the first thing to do after the discovery of poisoning is to disconnect the network.
There are many ways to disconnect the network. The simplest way is to dial the network cable behind the computer, which is also the simplest way. However, in practical applications, this is not necessary. After all, it is still annoying to go behind the computer. If a firewall is installed, you can directly disconnect the network from the firewall. If there is no firewall, you can right-click the "Network Neighbor" icon and select "attribute" in the pop-up menu ", in the displayed window, right-click "Local Connection" and set it to "disabled. If you are a dial-up user, you only need to disconnect the dial-up connection or disable the Moden device.
3. Back up important files.
If important data, emails, and documents are stored in your computer, you should immediately back up them to other devices, such as mobile hard disks and CDs, after the network is disconnected. Although the files to be backed up may contain viruses, it is much better to delete them when anti-virus software detects viruses.
What's more, after a virus attack, it is very likely that the system will not be able to enter. Therefore, backing up important files in time after poisoning is one of the most important ways to reduce losses.
4. Comprehensive Anti-Virus.
When you have no worries, you can scan and kill viruses. The scan and removal process consists of two parts: Full antivirus in Windows and DOS. Currently, mainstream anti-virus software can directly create DOS anti-virus disks. We recommend that you set anti-virus software first. For example, scan a file in a compressed package, scan an email, and handle a file containing viruses. For example, you can set it to "clear viruses" or "isolate ", instead of directly "deleting files", the purpose is to prevent important files from being deleted due to misoperations.
5. Change important data settings.
Because viruses and Trojans are often aimed at stealing users' personal data, some important personal data must be stored after comprehensive anti-virus operations, for example, resetting QQ and Email account passwords. This is especially true for Trojans discovered after detection and removal.
6. Check the network neighbors.
If you are a LAN user, check whether other computers on the network are also infected with viruses after processing the virus on your computer. This is because many viruses attack other computers on the network. Your computer is infected with viruses, which are very likely to be transmitted to other computers on the network. If it is not cleared in time, it is very likely that it will be re-transmitted.
In addition to Virus Cleaning on each computer, you can also install the Kingsoft network firewall. If there are viruses on other computers, the virus firewall will stop attacks. You only need to open the interception logs to find out which IP address sends the virus database, and then find the computer based on the IP address, and follow the above method for processing.
Computer viruses often happen to friends who like computers. We just need to calm down in front of the virus and think about emergency measures to avoid computer damage. If you are interested, you must take a look at the above emergency response skills!
