今天突然發(fā)現(xiàn)在C盤根目錄下藏著幾個(gè)奇怪的文件：arcldr.exe、arcsetup.exe和NTDETECT.COM。這幾個(gè)文件都是隱藏的系統(tǒng)文件，也不知道從哪里來(lái)的，用瑞星查了一下沒有報(bào)是病毒，網(wǎng)上查了一下沒人說(shuō)出個(gè)所以然來(lái)，最后還是一段英文說(shuō)明了問(wèn)題：

Verify Windows 2000 system files (Windows2000的系統(tǒng)驗(yàn)證檔案)
This stage checks each of the core system file in Win 2000 against a set of checksums and make sure they're valid. This includes NTLDR, NTDETECT.COM, ARCSETUP.EXE, and ARCLDR.EXE files, all of which are used during the boot process. If any of these files are damaged, they get replaced with fresh copies from either the Win 2000 CD-ROM or the OEM disk that you got supplied with your computer.

所以說(shuō)，這幾個(gè)文件都沒啥問(wèn)題，不是病毒。
