几天前,我的网站出现了问题。在所有ftp服务器中,我得到了一些名为google_verify.php的php文件,并在我的.htaccess文件中添加了以下文本:
<IfModule mod_php5.c>
php_value auto_append_file "google_verify.php"
</IfModule>
<IfModule mod_php4.c>
php_value auto_append_file "google_verify.php"
</IfModule>
这是google_verify.php文件:

我怀疑我的电脑感染了某种可以从我的ftp管理器读取我的ftp访问参数的病毒。
有没有人知道更多关于这种病毒的信息以及如何清理我的电脑?

我不是安全专家,但我的一个网站获得了相同的文件。根据我有限的知识和研究,发生的事情是您的网站被黑客入侵,而google_verify.php文件是注入攻击的一部分。
您还应该检查您网站的其他文件(特别是index.php / htm / html)并查找:
