If you want to learn kill-free technology: 1. basic assembly language 2. modify the tool (not the silly software ). for example, ollydbg. peditor. c32asm. myccl compound signature positioner. UE. OC. resource editor. there are also some shell check and shelling software (such as peid RL shelling machine ). the following are common kill-free methods and tools:
1. It is very important to prepare a non-shelled

About if and prevent the Android program to prevent the problem of restarting after 360kill, certainly we have searched a lot of methods, are not good, right, what elevated authority, what process priority, these things are not controllable, so there are some very insurance methods, Automatically restarts the program after it has been killed.We find that when we use 360 for program cleanup, some applications start up quickly and how do they do it? In fact, we have not seen their source code, it

Here are two tips to help you forcibly kill the "stubborn" virus process.
Scan and kill by process name
This method is implemented through the taskkill command in the WinXP system. before using this method, you must first open the system process list interface and find the specific process name corresponding to the virus process.

Batch kill mysql process if a large number of operations can be generated through a series of select statements, then theoretically these results can be batch processed. Www.2cto.com, but mysql does not provide the eval function for analyzing the result set. Therefore, you can only save the select result to a temporary file and then execute the commands in the temporary file. The specific process is as follows: mysql> SELECT concat ('

Kill-hup PIDhttp://blog.csdn.net/zhuying_linux/article/details/7031573Kill-hup PIDThe PID is the process identity. Use this command if you want to change your configuration without stopping and restarting the service. After making the necessary changes to the configuration file, issue the command to dynamically update the service configuration.By convention, when you send a pending signal (signal 1 or HUP), most server processes (all common processes)
