我的主目录中有 2 个未知文件（我对它们一无所知）。
我记得在我重新安装 ubuntu（升级到 18.04）之前，我在 /home 目录中有太多它们。
昨天我有一个，今天我有两个名为：
hs_err_pid2498.log和hs_err_pid2118.log。
hs_err_pid2118.log 的第一行（982 行）：

这些文件是什么？
我可以删除它们吗？（会发生什么？）
直到 2 或 3 个月前我才拥有类似的文件！
我认为当我使用tor服务（搜索或下载）时，会出现这些文件，因为我之前没有使用 Tor 下载东西（直到 2 或 3 个月前）。
如果是关于安装软件，请注意：我4天前几乎没有安装任何东西！
