This article mainly explains "how to prevent the execution of web script virus". The content of the explanation is simple and clear, and it is easy to learn and understand. let's follow the editor's train of thought to study and learn "how to prevent the execution of web script virus"!

I wonder if this has ever happened to you? While surfing the Internet is in high spirits, suddenly the IE window keeps opening until the resources are exhausted. Recently, not long after the author surfed the Internet, the computer has been frantically opening the IE window, resulting in the system taking up too much memory and crashing. Although I used IE 6 and was protected by a virus firewall, I still got hit.

Later, when I checked the data, I realized that I had been hit by a script virus. In fact, it's just something called "WSH" that is messing around. Script viruses cannot be executed without WSH. WSH, whose full name is "Windows Scripting Host", is a language-independent script interpretation mechanism based on 32-bit Windows platform provided by Microsoft, which enables scripts to run directly from the Windows desktop or command prompt. The program "WScript.exe" corresponding to WSH is a scripting language interpreter located in the folder where Windows is located, and most systems will have WSH after default installation. It is precisely because it enables scripts to be executed, and therefore provides a way for script viruses to spread.

WSH is supposed to allow system administrators to configure the desktop environment and system services to minimize management. So for the vast majority of ordinary users, it is not of much use, so as long as it is uninstalled to prevent the invasion of malicious viruses!

The specific methods are as follows: open [my computer] → [Control Panel] → [add / remove programs] in Windows 98 (or more than Windows NT 4.0), select "Windows installer", and then double-click the "Accessories" option to pop up the window. Uncheck the "Windows Scripting Host" item, and then click OK twice to uninstall it. After the author uninstalls it to surf the Internet, I have never encountered malicious code again, which seems to be very effective!

In addition, there are some common ways to prevent malicious scripts:

1. You can delete all actions against script files with the suffix "VBS, VBE, JS, JSE, WSH, WSF" in the file type by opening my computer, clicking [View] → [folder options] → [File Type]. So that these files will not be executed.

two。 Disabling all ActiveX plug-ins and controls and Java related in the IE settings can also avoid some malicious code attacks. The method is to open IE, click [tools] → [Internet options] → [Security] → [Custom level], in the "Security Settings" dialog box, all ActiveX plug-ins and controls and components related to Java can be prohibited. However, after doing so, we can no longer enjoy some beautifully made web pages.

3. Upgrade the system and IE in time and patch it. Choose a good antivirus software and upgrade it in time, don't easily browse some websites of unknown origin. In this way, most of the malicious code will be shut out by us.
