File.delete()方法问题.

import java.io.*;



public class SearchAutorun {

	public void search() throws IOException {

		String st = new String();

		st = "G:\\";

		File f = new File(st);

		String[] string = f.list();



		for (int i = 0; i < string.length; i++) {

			if (string[i].equals("autorun.inf")) {

				File newf = new File(st + string[i]);

				BufferedReader br = new BufferedReader(new FileReader(st

						+ string[i])); // 构建缓冲输入流.

				while (br.readLine() != null) { // 读取文件内容

					String s = br.readLine(); // 读取inf文件的一行

					String subs = s.substring(s.indexOf('=') + 1); // 分割字符串将等号后面的字符串划为一个新的字符串.

					File nf = new File(st + subs);// 构建病毒文件

					//System.gc();

					nf.delete(); // 删除病毒文件

				}

				System.out.println("删除了病毒文件");

				//System.gc();

				newf.delete(); // 删除autorun.inf文件.

				System.out.println("删除了自动运行文本.");

			}

		}
