Anti-Virus Defense layer concept analysis

Anti-virus software has been developing for 30 years and has become a necessary software for everyone's daily life. Most users do not have a deep understanding of anti-virus software. Baidu, Google, forums, or friends can query which anti-virus software works better. If a friend recommends anything, they can also use it, I did the same at school. Your friend may obtain information in the same way as you, and may cause subjective deviations. Today, we will introduce the concept of defense layer in anti-virus software.

First, what is anti-virus software?

Software that can clear viruses and Trojans and pose potential threats to users can be regarded as anti-virus software.

Anti-Virus Software in the industry has common technical features

1. signature detection and removal technology

Every anti-virus software requires the pattern scanning and removal technology. Every day, the software updates the virus database code to address known virus threats.

2. Active Defense Technology

Simple products use rule restrictions. Advanced Products Use simulated virus run track analysis to effectively intercept viruses before they are damaged.

3. heuristic Technology

By decompiling suspicious files and parsing program code, an Anti-Virus engine can determine the threat score. When the threat risk is high, effective defense measures are implemented to determine unknown viruses and suspicious files in advance, make accurate and effective judgments.

4. Virtual Machine Technology

Anti-Virus Software with virtual machine technology is more effective in the defense against disguised viruses. It can avoid false positives. Once the virus is exposed, it will be blocked without affecting the operating system.

5. System Repair Technology

Because the virus has tampered with key parts of the system and immediately cleared the virus, the original system must be restored to truly eliminate the impact on users. The system must repair the engine and play a role.

Functional modules: Firewall, privacy protection, anti-spyware, anti-spam, parental control, game mode, data backup, including unique anti-virus software technical features.
