只能用第三方软件，如果360，金山一类软件清理，另外C盘右键，属性，磁盘清理，清理下磁盘，

右键C盘打开属性——磁盘清理（D）。

通过分区助手增加C盘空间。





提示：安装软件时可以尽量不要安装到c盘。

追问

格式化是不是所有东西都没了

追答

是的。但一般不能格式化，因为windows 系统安装在C盘。格式化则可能不能启动。

电脑卡的原因不止是木马病毒导致，我们还需要对电脑c盘清理以及整个系统优化，这就是所谓的电脑系统垃圾，经常保持定期清理系统垃圾，可以有效提高系统稳定性。
如果是电脑中存在大量垃圾，以及开机自动启动那些娱乐软件会很大程度影响系统性能。
解决办法：
使用腾讯电脑管对电脑进行系统清理，并且使用软件自带的开机加速优化，禁此一些娱乐软件开机自动启动 以便提高电脑开机速度与系统速度。之后建议清理垃圾注册表和系统一些垃圾插件。
　为了尽可能保持电脑性能稳定，建议一星期左右用管家清理垃圾与插件等一次。
