A small enter password dialogue box appeared after powering on my laptop computer
Hi,
After downloading and unpacking a .tar.gz package and unpacked it in one of the
directories, I could not login my computer.
Whenever I turn on my computer, a small enter password dialogue box comes on. I tried entering a few of my passwords ,but still could not login my computer.
I also can not call up the BIOS screen like before. A normal boot for my computer would be a selection screen comes on for the selection of OS.
The password dialogue box should not be asking for the BIOS password or the power-on password
because I have not set those passwords.
A normal boot would have been a splash screen came on and then
automatically booting into Linux if I did not select to boot into
Window 7.
In this incident, the Linux splash screen does not came on, and instead,
a blank screen with the small dialogue box asking for password came on.
I tried with a few of my know passwords but could not login my laptop
And the next day, the normal login splash screen from where I select which OS to boot into
came back on as in a normal boot and everything seemed to be O K for now.
But I guess I should change some of my passwords - those I have used to try to login.
You probably need to assume something like, "a root-kit has just been installed." Or something along those lines. There is no reason for a password prompt to mysteriously appear at boot time ... let alone to then just-as-mysteriously disappear.
If you have not resolved this problem, the very minimum information you should post is the name of the tar.gz file, the location from which you downloaded it and the location in which you 'unpacked' it. Just 'unpacking' or extracting the file should not present what you saw.
Too resemble BIOS password. I agree that you had not touched it, but can you check that ?
Still you able to login into BIOS setting by pressing some magic key ?
Distribution: Debian Sid AMD64, Raspbian Wheezy, various VMs

I have looked into my BIOS settings and chances were the enter password prompt was indeed from the
BIOS because I did see in BIOS, User Password was indicated as "Not Installed".
So, in order to check and see, and for the very first time, I set the User Password in BIOS. And when
I powered up my laptop, the enter password dialogue box did come on. And I logged in with my password.
Now, BIOS indicates User Password as "installed", because I have set it.
The tar.gz file downloaded was for the installation of WordPress on my laptop for learning purposes, and
it runs O. K. (strangely thought I do not need to do ./configure). The name of the file was wordpress-4.8.tar.gz
which I downloaded from http://wordpress.org/download .
So, for now, I have to assume my laptop has been compromised.
Would certain hardware issues might have been the cause of this problem ?
