How to choose a Web Trojan Protection Tool

Web TrojanThe selection criteria for protection tools are as follows:

Ability to scan Zip packages

During Web Trojan propagation, the ZIP package isTrojanFavorite places to hide. When a user downloads a ZIP attachment from a Web mail client and opens it, it is possible that the trojan is already running locally when the user is unaware. And try to infect other users. Therefore, the author believes that when selecting a Web Trojan protection tool, we first need to confirm the scanning capability of this protection tool for Zip compressed packages.

Generally, most Web Trojan protection tools already have this ZIP package scanning tool, but they can only scan single-layer Zip packages. In fact, users may all have experience in this area. Select the ZIP package, right-click it, and find that the decompressed file is still a compressed package. Then decompress the package to obtain a compressed package. After repeating this several times, the final result is the file itself. This involves multi-layer ZIP compression files. When receiving this file, be careful. This is probably a Web Trojan.

Nowadays, many Web anti-Trojan tools only have single-layer ZIP compressed package scanning tools. In this case, when two or more layers of data are compressed, the trojan hidden in the data cannot be used. Many Trojans intentionally package a file multiple times to avoid monitoring by using the protection tool.

Therefore, when selecting a trojan protection tool, you need to select the ZIP package that can be scanned, especially the protection tool that supports multi-layer scanning. The effect will be better.

Whether the protection tool can scan memory

When a user opens a webpage and the webpage has a Trojan horse, the Trojan horse enters the memory of the user host. Then, find the processes that can be used in the memory (such as the defects of a process in the operating system ). This is a traditional method and a harmful means of Trojan intrusion.

This requires that the trojan protection tool must also have the memory scanning capability. The memory scan is used to find the latest Trojan Horse inserted into the address space of other processes. In addition, it should be noted that it is dangerous to check the Trojan horse in the memory. If the process is mistakenly killed by other available processes (even if the process is infected by a Trojan), the host or the system in use will crash.

This requires us to consider the stability of the anti-Trojan tool. Especially when the trojan in the memory is involved in automatic scanning and removal, if the key process that may cause the user's system to crash, it is best to send a reminder like a user before clearing it. After the user saves the relevant data

Need to be able to analyze unknown viruses

A high foot, a high devil. In general, Trojans are always a step ahead of protection tools. That is to say, after a trojan arrives (after a period of time), the corresponding protection tool can identify and kill the Trojan. This means that after a trojan is discovered, a considerable number of users are already in use. This will undoubtedly cause great losses to users.

Therefore, when selecting a trojan tool, it is best to check whether this anti-Trojan tool can detect unknown viruses. For example, I recommend an Antiy Trojan protection tool. This is a professional Web Trojan Detection and system security tool. The most important feature of this tool is that it not only detects known Trojans, but also discovers some unknown Trojans. This is mainly because this tool has an Intelligent Analysis System.

The Intelligent Analysis System can determine whether a process is a trojan or infected by a trojan based on the characteristics and running status of a process. Then, the user is reminded. However, due to its uncertainty, the general system does not automatically scan and kill, but only reminds users to pay attention to this process. When users think that this process Trojan is more likely, for security reasons, you can query and kill this process. This can avoid unnecessary damage to users by Trojans to the greatest extent. For applications with high security levels, such as online banking, pay special attention to this point when choosing a trojan protection tool.

Trojans are tricky, so choosing the right Web Trojan protection tool is very important. I hope you will learn more about this. Next article: How to choose a Web Trojan Protection Tool
