Copy Code code as follows:
Run-->cmd.exe
First use tasklist >>list.txt to get the PID value of the virus
Then using taskkill/f/t/pid PID value,

Introduction to Anti-Virus engine design
1. Introduction
The main content of this article is as follows: Design and compile an advanced anti-virus engine. First, we need to explain the word "advanced". What is "advanced "? As we all know, traditional anti-virus software uses static Scanning Technology Based on signatures, that is, to find a specific hexadecimal
In our network life, computer viruses pose a major threat to us. We are very concerned about how to prevent viruses. In fact, the prevention of computer viruses is not simply a few words. Some of us have very many mistakes in our understanding, next let's take a look at some of the mistakes we encounter when dealing with computer viruses.1. the DIR operation on the infected floppy disk will cause the hard disk to be infected (wrong)
If the computer memory does not contain viruses, the computer w
Virus and Anti-Virus products are born enemies. Due to the endless existence of viruses, this field of Anti-Virus products will naturally be divided by many vendors, as a result, multiple Anti-Virus engine technologies have been developed.
The Anti-Virus engine is the key to
