[IT168]When a netizen plays Flash animation, online video watching, and anti-virus in the IE browser, the page often appears "This page has potential harm to Active X, therefore, the dialog box on this page cannot be correctly displayed. This indicates that there is no embedded ActiveX plug-in on this page and you need to prompt for installation. ActiveX plug-ins are also called OLE controls or OCX controls. They are software components or objects that can be inserted into WEB pages or other applications. The prerequisite for installing ActiveX plug-ins is to download and then authenticate the plug-in before the end user can confirm and agree to install the plug-in. pages embedded with ActiveX Scripts may become very slow and even cause the browser to lose response instantly. If you do not treat ActiveX plug-ins correctly, it is equivalent to opening the door for hacker intrusion. On the internet, ActiveX plug-in software has the following features: Generally, You need to download and install the software separately. ActiveX plug-in is used when you browse a specific webpage, the IE browser automatically downloads and prompts you to install the SDK. Advantages and disadvantages of ActiveX plug-ins
Although ActiveX plug-ins provide convenience, virus and Trojan Horse makers also recognize their advantages. They embed harmful programs into the web page. When users browse the Web page, they install ActiveX plug-ins, viruses and Trojans have quietly penetrated into your computer, and many users may not have noticed that your computer is in danger. It can be seen from the application of ActiveX plug-in above that it is very easy to call ActiveX plug-in on the webpage, making ActiveX plug-in a good parasitic infectious medium for virus Trojans. Each ActiveX plug-in has different purposes, so it has different functions. In the early stage, in order to better protect your computer information from being stolen, as long as the webpage prompts that you need to install it, we will follow the prompts. Today, hackers use it to gain greater benefits. Installing too many ActiveX plug-ins will consume too much resources, resulting in unstable system operation. It is easy to infect viruses and trojans when browsing the Web page. Plug-ins are prone to conflicts. These insecure and unstable factors also lead to users' dislike of ActiveX plug-ins.
Correct treatment of ActiveX plug-ins
To ensure the stable operation of the system, prevent plug-in programs from conflict, and intrude into viruses and Trojans, it is very important to strictly manage ActiveX plug-ins. ActiveX plug-ins should be managed from the following three aspects to Facilitate network security maintenance.

1. Shield useless plug-ins
From the perspective of ActiveX plug-in usage, there are actually a few ActiveX plug-ins that are actually useful. You can determine which ActiveX plug-ins are useful Based on the accessed content, and those are useless plug-ins. For general Internet users, there are almost some Windows system update controls and Flash controls, and some may want to use the online banking system or other services to install ActiveX. In fact, we can install all these useful ActiveX plug-ins. Next, we will block the online installation of all ActiveX plug-ins in browser settings, so that no matter what ActiveX plug-ins will pop up in the future, you can also use the following two steps to block useless plug-ins.

Step 1: first use IE to access the page where you need to install ActiveX plug-ins, such as the Microsoft Windows Update site and the site with Flash, select "yes" when prompted to install ActiveX.

Step 2: After all ActiveX programs are installed, select "Tools> Internet Options" in IE, switch to the "Security" tab, and click "Custom Level, in the pop-up "Security Settings" window, set "Download unsigned ActiveX control" and "Download Signed ActiveX Control" to "disabled ". I

When you confirm that ActiveX is required for some websites, restore the above settings to "default", refresh the page for installation, and then set it to "disabled" after installation ". There are more and more ActiveX plug-ins available on the Internet. Although most of them can enrich web content and enhance the functions of IE browsers, installing too many ActiveX plug-ins will cause system instability, I suggest that you install ActiveX plug-ins selectively to shield ActiveX plug-ins that are not needed. Although some ActiveX plug-ins can be blocked by modifying the registry, the operation is troublesome. Here I suggest using a third-party plug-in management tool, so that the shielding operation of ActiveX plug-ins becomes simple.

2. manage existing plug-ins
The ActiveX plug-in management function is built in IE browser, which can be used to manage existing plug-ins. Click "Tools> Manage Add-on" in IE, the "Manage Add-on" Setting dialog box is displayed, and then select "existing add-on in Internet Explorer" in the "show" drop-down list box ", in this way, all existing ActiveX plug-ins in the system are displayed in the list box. It is very easy to disable an ActiveX plug-in. Select the ActiveX plug-in the list box, select the "Disable" option in the "Settings" column below, and click "OK. You can also use 360 security guard to perform regular scans to clear insecure ActiveX plug-ins. II

The preceding steps allow you to correctly treat ActiveX plug-ins. The ActiveX plug-ins in the system are strictly managed. This ensures the stable operation of the system to the maximum extent and prevents the invasion of viruses and Trojans, the network can be more secure.
