What should I do if the Windows 7 system computer is poisoned?

When using a computer to access the Internet, entering some unsafe websites may cause computer poisoning. After the computer is poisoned, abnormal processes may occur and unknown programs are running. This will seriously slow down the running speed of the computer, even in the case of When I open the browser, I will try to run some ActiveX controls, debug scripts, etc. What should I do if this computer is poisoned?

First, do not restart

Many people feel after the poisoning, first of all think the first thing to do is to restart the computer. In fact, this approach is extremely wrong. When the computer is poisoned, if it is restarted, it is very likely to cause more damage.

Second, disconnect the network immediately

Because the virus will not only slow down the computer, but also destroy the data on the hard disk, and may also send your personal information, virus Etc., further increase the harm. In this regard, after discovering poisoning, the first thing to do is to disconnect the network.

There are many ways to disconnect the network. The easiest way is to go to the back of the computer and dial the network cable. This is the most simple method. However, in the actual application, we do not need such trouble, after all, it is more annoying to run behind the computer. If a firewall is installed, you can disconnect the network directly from the firewall. If you do not have a firewall, you can right-click the “Network Neighborhood” icon and select “Attributes” from the pop-up menu. Right-click in the window that opens. ;local connection”, set it to “disable” If it is a dial-up user, you only need to disconnect the dial-up connection or turn off the Moden device.

Third, backup important files

After poisoning, should I immediately perform anti-virus, I personally think that if there is no important file in the computer, then how to operate does not matter, at most I format the hard disk re-install. However, if important data, emails, and documents are stored on your computer, you should back them up to other devices immediately after disconnecting the network, such as moving hard disks, CDs, and so on. Although these files to be backed up may contain viruses, this is much better than removing them from antivirus software.

Moreover, after the virus is attacked, it is very likely that the system will not be able to enter the system. Therefore, timely backup of important documents after poisoning is one of the most important ways to mitigate losses.

Fourth, comprehensive anti-virus

When there is no worries, we can carry out virus detection. Killing and killing should include two parts, one is to perform comprehensive anti-virus under Windows system, and the other is to perform anti-virus under DOS. At present, mainstream anti-virus software can generally directly produce anti-virus disks under DOS.

In anti-virus, users are advised to make the necessary settings for anti-virus software. For example, scanning files in a compressed package, scanning emails, etc., and processing the files containing viruses, for example, it can be set to "Clear Virus" or "Isolate" instead of directly deleting files. The purpose of this is to prevent important files from being deleted due to misuse.

V. Changing important data settings

Because viruses and Trojans often steal personal data for users, after the full anti-virus operation, some important individuals must be Data, such as QQ, Email account password, etc. are reset. Especially after the killing, it was found to be a Trojan horse program, especially for this work.

VI. Checking Network Neighborhoods

If you are a LAN user, after you have processed your own computer virus, check if other computers on the network are also infected with the virus. Because many viruses will attack other computers on the network after the attack. The virus in your own computer is very likely to be transmitted to other computers on the network. If you don't clean it up in time, it's very likely that you will reverse the infection.

In addition to the comprehensive virus removal on each computer, you can also install the virus firewall of Jinshan Net Dart. If there are other computers on the network, the virus firewall will keep going. To block the attack, we only need to open the log of its interception, we can know which IP address is sent by the virus database, find the computer according to the IP address, and then process it according to the above method.

The above is some solution after computer poisoning. If the user accidentally infects the virus while using the computer, try the above method. The last thing to remind everyone is that it is best not to visit and download some unsafe websites and software.
