杀杀杀
这两天公司闹蠕虫，会在每个目录里放一个_desktop.ini文件。杀毒软件可以杀掉病毒，但是不会清除文件。今天自己机器也感染了，写了个小工具做这个清除工作，竟然删掉了十一万个残留文件http://www.agoit.com/images/smiles/icon_confused.gif 。代码如下：import java.io.File;import java.io.FileFilter;public class FileCleaner {//file name to be deletedprivate String fileName = null;//deleted file number counterprivate int counter = 0;public FileCleaner(String fileName){if(fileName == null || fileName.length() <= 0)throw new IllegalArgumentException();this.fileName = fileName;}/** * entry method ** @param path directory to be processed */public void cleanFile(String path){File dir = new File(path);if(!dir.isDirectory())return;processDir(dir);}/** * returns the deleted file number ** @return */public int getDeletedFileCount(){return counter;}private void processDir(File tmp) {System.out.println("Start to check " + tmp.getAbsolutePath());File[] acceptedFiles = tmp.listFiles(new FileFilter(){public boolean accept(File f){if(f.isDirectory() || fileName.equals(f.getName()))return true;elsereturn false;}});if(acceptedFiles != null && acceptedFiles.length > 0){for(int n=0;n<acceptedFiles.length;n++){if(acceptedFiles.isDirectory()){processDir(acceptedFiles);}else{if(fileName.equals(acceptedFiles.getName())){acceptedFiles.delete();counter++;System.out.println(tmp.getAbsolutePath() + "\\" + fileName + " is deleted!");}}}}}//----------------------------------------------------------private static String help(){StringBuffer help = new StringBuffer(128);help.append("Delete all files with given name in the specified directory and its subdirectories. \n\n");help.append("command \n\n");help.append("For example: \n");help.append(" java -jar FileCleaner.jar _desktop.ini c:/ d:/ e:/");return help.toString();}public static void main(String[] args){if(args == null || args.length <= 1){System.err.println(help());System.exit(0);}FileCleaner fc = new FileCleaner(args);for(int n=1;n<args.length;n++){fc.cleanFile(args);}System.out.println("Finish deleting " + args + ", total " + fc.getDeletedFileCount() + " deleted!");}}
