Six tricks: Correctly handle computer viruses

I often walk by the river. How can I leave my shoes wet? Various viruses on the Internet are constantly spreading. As computers connected to the Internet, although we have already taken various measures, we still cannot avoid them. We will try again without any worries. Now we have learned a lot about how to prevent computer viruses, but we know little about how to deal with computer viruses that have been poisoned. Next we will introduce some emergency measures after poisoning.

1. Do not restart

Generally, when you find abnormal processes, unknown program running, or a computer running slowly, or even ie often asks whether to run certain ActiveX controls or debug scripts. At this time, you 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. Instant network disconnection

After a virus attack, it not only slows down the computer, but also damages the data on the hard disk. It may also send your 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, we do not need to be so troublesome. 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.

Iii. Backup of important files

I personally think that if there are no important files in the computer, it doesn't matter how to operate it. At most I will format the hard disk and reinstall it. However, if important data, emails, and documents are stored in your computer, you should immediately back up the data to another device after the network is disconnected, such as a mobile hard disk or a CD. 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.

Iv. Comprehensive Anti-Virus

When there is no worries, we 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 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, then the virus firewall will stop the attack. We only need to open the interception log 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.
