现象
Phenomenon：

上周末突然收到备注为CSDN，身处澳洲的网友加微信，抱怨并请求帮助：浏览器被恶意软件劫持了，即anysearch 劫持了他的浏览器，修改了其主页，而且主页再也不能被还原成默认值，是不可用状态。他已经按照我前面的某篇文章进行了移除，但是过段时间，这个问题又会出现。

看到这里，我首先意识到他没有处理干净，所以只是治标不治本。后来他又重新装了一次那个恶意插件，把信息提供给我分析，经过仔细筛查后，提供给其解决方法。终于经过简单处理后他成功移除了相应的恶意插件，浏览器的主页也恢复了正常。

At the end of last week, I suddenly received the comment CSDN. The netizens in Australia added wechat, complained and asked for help: the browser was hijacked by malware, that is, anysearch hijacked his browser, modified his homepage, and the homepage can no longer be restored to the default value, which is unavailable. He has been removed according to one of my previous articles, but after a while, this problem will appear again.

Seeing this, I first realized that he didn't deal with it thoroughly, so he just treated the symptoms rather than the root cause. Later, he reinstalled the malicious plug-in, provided me with information for analysis, after careful screening, and provided solutions. Finally, after simple processing, he successfully removed the corresponding malicious plug-ins, and the browser's home page also returned to normal.

分析
Analysis：

根据用户反馈提供的信息，收集如下：

Based on the information provided by user feedback, the collection is as follows:

经过对上述文件的分析，初步怀疑跟下述路径及其关联的程序有关：

nmmhkkegccagdldgiimedpiccmgmieda和pkedcjkdefgpdelpbcmbmeomcjbeemfm 命名所对应的Chrome插件

Library/Application Support目录下的Macromedia和ResearchSoft 文件目录

~/Library/Application Support目录下的com.Aphrodite.Results文件目录

Based on the analysis of the above documents, it is preliminarily suspected that it is related to the following paths and related procedures:

The corresponding chrome plug-in named by nmmhkegccagdldgiimedpiccmgmieda and pkedcjkdefgpdelpbcmbmeomcjbeemfm

Macromedia and researchsoft file directories under the library/application support directory

~/com.aphrodite.results under the library/application support directory

处理方法：
Approach:

首先，移除上述截图中的profiles文件下的所有配置，恢复成空白默认值。

First, remove all the configuration under the profiles file in the screenshot above and restore it to the blank default value.

其次，移除上述路径下的配置文件(根据自己发现的实际路径进行引用)，如果有。检查是否还存在相关的其他配置文件，杀掉该进程，再重启电脑。

Secondly, Remove the configuration file under the above path(reference according to the actual path you find), if any. Check if there are other related configuration files, kill the process, and restart the computer.

但针对本次的样本，在本地文件夹还可能有其它的一些恶意配置存在，需要一并移除，以免死灰复燃！

But for this sample, there are some other malicious configurations in the local folder, which need to be removed together to avoid resurgence!

rm -rf ~/Library/Application\\ Support/ResearchSoft
rm -rf ~/Library/Application\\ Support/Macromedia
rm -rf ~/Library/LaunchAgents/AphroditeResults dldr.adload.cfjcc*
rm -rf ~/Library/LaunchAgents/com.pcv.hlprmcp.plist
rm -rf /Library/LaunchAgents/AphroditeResults dldr.adload.dmrct.plist
rm -rf /Library/LaunchDaemons/com.Aphrodite.Results
rm -rf ~/Library/Application\\ Support/Google/Chrome/Default/Extensions/nmmhkkegccagdldgiimedpiccmgmieda
rm -rf ~/Library/Application\\ Support/Google/Chrome/Default/Extensions/pkedcjkdefgpdelpbcmbmeomcjbeemfm

实际上，上述文件对当前Mac系统的影响微乎其微，即使有误删，后期根据需要可以重新安装，所以删除不会影响系统的正常运行。

In fact, the above files have little impact on the current Mac system. Even if it is deleted by mistake, it can be reinstalled as needed later, so the deletion will not affect the normal operation of the system.

可疑文件全部移除完成后，最好重置浏览器，或者移除之前保存的状态数据

After all the suspicious files have been removed, it is best to reset the browser or remove the previously saved state data.

~/Library/Saved\\ Application\\ State/com.apple.Safari.savedState
~/Library/Saved\\ Application\\ State/com.google.Chrome.savedState

再启动查看是否恢复正常。

Restart to see if it returns to normal.

忠告：
Advice：

1，苹果电脑要更新和下载软件尽量去App Store，其他浏览器突然弹出的说电脑有问题或者软件需要更新，都尽量不要点！！！！

2，电脑设置中安全设置，选项选择只安装认证过的软件！！！

3，要使用破解版软件，就必须做好被安装广告和恶意插件的心理准备！

1, Apple computer to update and download software as far as possible to the App Store, other browsers suddenly pop up saying that the computer has a problem or the software needs to be updated, try not to point! ! ! !

2, the security settings in the computer settings, the option to choose only installed certified software! ! !

3. To use the cracked version of software, you must be mentally prepared to install advertisements and malicious plug-ins!
