我的免费邮箱经常收到一封主题为:Mail Delivery (failure chzhbakhn@avl.com.cn)的邮件;其内容为:If the message will not displayed automatically,follow the link to read the delivered message.Received message is available at:www.avl.com.cn/inbox/chzhbakhn/read.php?sessionid-5410 还附有一个扩展名为.scr的屏保附件.我想知道这是怎么引起的,难道这就是垃圾邮件,如果是,我该怎么来防止它.
