My computer was tampered. I found the size of /bin/login is
very large.
ls -l /bin/login
-rwxr--r-- 1 root root 279484 ...
I want to overwrite it, even if I do so under "single user
mode", still fail.
Who can tell me how to remove or replace it?

boot with a floppy, mount root fs of your hd somewhere, (eg. /mnt)
then you can replace /mnt/bin/login

不用那么烦琐。因为该文件被人设置成 ext2fs 格式。
