很久的风行就是用的这种方法来防止用户删除它。
很久以前的一段时期也用次方法防U盘病毒
如下所示
:
防U盘病毒的原理就是在每个盘创建一个这样的文件
下面先接受几个win API
DWORD WINAPI GetLogicalDriveStrings(<span style="white-space:pre"> </span>//获取磁盘 _In_ DWORD nBufferLength, _Out_ LPTSTR lpBuffer );
<span style="color: rgb(69, 69, 69); font-family: 'Segoe UI', 'Lucida Grande', Verdana, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 20.0060005187988px;"> Fills a buffer with strings that specify valid drives in the system.</span>
第二个API
BOOL WINAPI CreateDirectory( _In_ LPCTSTR lpPathName, _In_opt_ LPSECURITY_ATTRIBUTES lpSecurityAttributes ); <span style="color: rgb(69, 69, 69); font-family: 'Segoe UI', 'Lucida Grande', Verdana, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 20.0060005187988px;"> Creates a new directory. </span>
下面是代码
#include "stdafx.h" #include <windows.h> void ImmuntiyAutoRun() { //建立无法删除的文件夹 char szDriverStr[MAXBYTE] = { 0 }; DWORD dwLen = GetLogicalDriveStringsA(MAXBYTE, szDriverStr); for (int i = 0; i < dwLen; i+=4) { char szRoot[4] = {}, szPath[MAX_PATH] = { 0 }; strncpy_s(szRoot, &szDriverStr[i], 4); strcpy_s(szPath, szRoot); strcat_s(szPath, "autorun.inf"); if (!CreateDirectoryA(szPath, nullptr)) printf_s("Error:%d", GetLastError()); strcat_s(szPath, "\\anti......\\"); if (!CreateDirectoryA(szPath, nullptr)) printf_s("Error:%d", GetLastError()); } } int _tmain(int argc, _TCHAR* argv[]) { ImmuntiyAutoRun(); getchar(); return 0; }
这样就会在每一个盘下面创建一个尾部带"....."的畸形文件夹。
但注意的是,用win API 可以把他删除哦。
BOOL WINAPI RemoveDirectory( _In_ LPCTSTR lpPathName );
以上就是 简单的反U盘病毒(删除不了的畸形文件夹)的内容,更多相关内容请关注PHP中文网(www.php.cn)!

The combination of C# and .NET provides developers with a powerful programming environment. 1) C# supports polymorphism and asynchronous programming, 2) .NET provides cross-platform capabilities and concurrent processing mechanisms, which makes them widely used in desktop, web and mobile application development.

.NETFramework is a software framework, and C# is a programming language. 1..NETFramework provides libraries and services, supporting desktop, web and mobile application development. 2.C# is designed for .NETFramework and supports modern programming functions. 3..NETFramework manages code execution through CLR, and the C# code is compiled into IL and runs by CLR. 4. Use .NETFramework to quickly develop applications, and C# provides advanced functions such as LINQ. 5. Common errors include type conversion and asynchronous programming deadlocks. VisualStudio tools are required for debugging.

C# is a modern, object-oriented programming language developed by Microsoft, and .NET is a development framework provided by Microsoft. C# combines the performance of C and the simplicity of Java, and is suitable for building various applications. The .NET framework supports multiple languages, provides garbage collection mechanisms, and simplifies memory management.

C# and .NET runtime work closely together to empower developers to efficient, powerful and cross-platform development capabilities. 1) C# is a type-safe and object-oriented programming language designed to integrate seamlessly with the .NET framework. 2) The .NET runtime manages the execution of C# code, provides garbage collection, type safety and other services, and ensures efficient and cross-platform operation.

To start C#.NET development, you need to: 1. Understand the basic knowledge of C# and the core concepts of the .NET framework; 2. Master the basic concepts of variables, data types, control structures, functions and classes; 3. Learn advanced features of C#, such as LINQ and asynchronous programming; 4. Be familiar with debugging techniques and performance optimization methods for common errors. With these steps, you can gradually penetrate the world of C#.NET and write efficient applications.

The relationship between C# and .NET is inseparable, but they are not the same thing. C# is a programming language, while .NET is a development platform. C# is used to write code, compile into .NET's intermediate language (IL), and executed by the .NET runtime (CLR).

C#.NET is still important because it provides powerful tools and libraries that support multiple application development. 1) C# combines .NET framework to make development efficient and convenient. 2) C#'s type safety and garbage collection mechanism enhance its advantages. 3) .NET provides a cross-platform running environment and rich APIs, improving development flexibility.

C#.NETisversatileforbothwebanddesktopdevelopment.1)Forweb,useASP.NETfordynamicapplications.2)Fordesktop,employWindowsFormsorWPFforrichinterfaces.3)UseXamarinforcross-platformdevelopment,enablingcodesharingacrossWindows,macOS,Linux,andmobiledevices.
