Anti-defense, evidence of malware invading the computer

Do you think that as long as there is anti-virus software, your computer can be poisoned? Then you are wrong. When our computer found a virus prompt, those viruses have invaded your computer, stealing your information, and they ran through the firewall and blatantly moved on the ages. What we have to do is to kill them in the cradle before they invade. Sherlock Holmes once said that when you take something away, you will leave something behind. The same is true for the same virus, so what we have to do today is to find evidence that the virus left behind on our computer.

Evidence 1: Homepage links have been tampered with

If you haven't made adjustments and found that the browser's default home page has changed, it's very likely that the system is infected with malware. Similarly, when you use Baidu search, click on the connection provided by Baidu, but it is directed to a random connection. This type of situation indicates that the system is infected by a virus or malware.

Evidence 2: The browser cannot access the Internet

When the network connection is normal (this can be easily confirmed by the ping command), but the Internet cannot be accessed, causing this problem. It is very likely that the system is infected with malware. At this time, all we have to do is to check the settings carefully and enter the browser's network connection project to ensure that no proxy server is set up. If this is the case, and you know that you are not using a proxy server, then the system is infected with malware.

Evidence 3: A decline in system performance

The notoriety of malware is that it can cause system performance to degrade, whether it is a network connection or the speed at which an application runs. Of course, just a drop in system performance does not mean that it is infected with malware. Since many other issues can cause system performance degradation, I recommend taking steps first to deal with system performance degradation (the usual measures are disk defragmentation, memory increase, etc.). If the system performance is still not improved after taking the necessary measures, it may be caused by malware.

Evidence 4: Focus on pop-ups

A potential sign of malware infection is the embarrassing pop-ups. Sometimes the user's computer pops up a porn window, which makes the user both angry and angry. Unexpected pop-ups (especially those that do not start with a web browser) are a sign that the system has been infected with malware. The key issue is that at this time, malware often cannot be deleted in standard mode; instead, you must restart the system and switch to safe mode. In order to clean up all parts of the malware, you need a powerful anti-malware tool to remove it.

Malware attacks can sometimes be hard to prevent, but we can take precautions from the tricks they use. In the process of using the computer in peacetime, pay more attention to the evidence of the above mentioned virus crimes, I believe that they can be killed in the cradle, and you also have a green Internet environment.
