Linux 桌面残留清理

记录 Linux 上清理流氓软件残留的实战经验。以 CC Switch 为例。

核心教训

流氓软件（尤其 Windows 软件的 Linux 移植版）卸载后会在多处留下残留，需要系统性清理。

CC Switch 残留清单

路径	类型	清理方式
~/.config/autostart/*.desktop	自启动项	rm
~/.local/share/applications/*.desktop	应用入口	rm
~/.config/mimeapps.list	MIME 类型关联	编辑器移除 x-scheme-handler/ccswitch 行
~/.config/deepin/dde-desktop/dde-desktop.conf	Deepin 桌面配置	Python configparser 移除含 cc 的项
~/.config/deepin/dde-launchpad/item-arrangement.ini	Deepin 启动器配置	编辑器移除 CC Switch.desktop
~/.local/share/deepin/ApplicationManager/storage.json	Deepin 应用商店记录	Python JSON 移除对应 key
~/.cc-switch/	用户数据	rm -rf
~/.config/com.ccswitch.desktop/	独立配置目录	rm -rf
~/.local/share/com.ccswitch.desktop/	独立数据目录	rm -rf
/usr/share/applications/CC Switch.desktop	系统级桌面入口	需要 sudo
~/Desktop/CC Switch.desktop	桌面软链接	rm

    # 1. Desktop 软链接
    desktop_link = f"{HOME}/Desktop/CC Switch.desktop"
    if os.path.islink(desktop_link) or os.path.exists(desktop_link):
        os.remove(desktop_link)

                d = json.load(f)
            keys = [k for k in d.keys() if "cc" in k.lower() or "switch" in k.lower()]

    # 8. 用户数据目录
    for d in [f"{HOME}/.cc-switch",
              f"{HOME}/.config/com.ccswitch.desktop",

    sys_desktop = "/usr/share/applications/CC Switch.desktop"
    if os.path.exists(sys_desktop):
        print(f"Need sudo to remove: {sys_desktop}")
        print(f"  sudo rm \"{sys_desktop}\"")

if __name__ == "__main__":
    remove_cc_switch()

Deepin ApplicationManager storage.json 清理（Sudo 版）

import json
path = '/home/muc/.local/share/deepin/ApplicationManager/storage.json'
with open(path) as f:
    d = json.load(f)
keys = [k for k in d.keys() if 'cc' in k.lower() or 'switch' in k.lower()]
for k in keys:
    del d[k]
with open(path, 'w') as f:
    json.dump(d, f, indent=2)
print('Done')

关键发现

1. Deepin 有自己独立的应用管理器，storage.json 路径：~/.local/share/deepin/ApplicationManager/storage.json（不是 /root/ 下）
2. MIME 类型不止 mimeapps.list，WM_CLASS 也需要清理（StartupWMClass=cc-switch 在 .desktop 文件中）
3. 桌面入口不只在 applications 目录，Deepin 还会在 ~/.config/deepin/dde-desktop/ 和 ~/.config/deepin/dde-launchpad/ 中记录
4. 系统级 desktop 文件必须 sudo 才能删
