VC++信息安全编程（6）实现杀毒程序，杀灭D3病毒范例

	 

	下面我们用代码亲自来实践一个杀毒程序，清除程序的可读可写，并扫描程序的特征码，对病毒进行删除

	static char THIS_FILE[] = __FILE__;

	#endif

	 

	UINT ThreadProc(LPVOID param){

	CScanDiskDlg *ScanDisk=(CScanDiskDlg*)param;

	CString part;

	int i=0;

	int cy=ScanDisk->m_Disk.GetLength()/2;

	do{

	       part=ScanDisk->m_Disk.Mid(2*i,2);

	    ScanDisk->SearchFolder((char*)part.GetBuffer(0));  

	       i++;

	}while(i<cy&&ScanDisk->Status);

	 

	char s[256];

	sprintf(s,"扫描的文件总数=%d",ScanDisk->TotalFileNum);

	ScanDisk->m_Static.SendMessage(WM_SETTEXT,0,(LPARAM)(LPCTSTR)s);

	return 0;
