Self-writing password

Question

Hello,
I have a problem with my laptop. I'm writing to you via my cellphone because I can no longer access my laptop.
When I open it, it endlessly types a password on its own. I plugged in another keyboard thinking that I had a stuck key, but it does the same thing with an external keyboard.
I tried to boot into safe mode, but it does the same thing.
I also removed the battery and the cord, then held down the Power button for 15 seconds before putting the battery back, but that didn't fix anything.
I thought I probably have a virus; otherwise, what could explain this, and more importantly, how can I regain control of my computer?
I have a Samsung running Windows 7.
Thank you for your help!

Configuration: Android / Chrome 73.0.3683.90

Hello,

The stuck key symptom seems the most likely, and plugging in a wired external keyboard won't change the fact that the stuck key is registered by the computer.
So I suggest you check each key on your keyboard and gently dust underneath each key using a brush.

I have looked at several keys with discouragement, I must admit.
I am at the stage of trying to bypass my password so that at least Windows opens, which would help me figure out which key is stuck if that's the problem.
I noticed that when I got to the repair stage and had to choose the language for Windows, the dropdown menu was out of control; I couldn't select Canadian... I tried to get there, but it was scrolling without letting me choose, so I think it ended up doing a repair in Arabic????
Is it normal to see the "crazy" menu with a stuck key and not be able to select the country?
Thank you.

By mistake, I registered that it was resolved, but it is not at all.
Here is an image of what my keyboard writes on its own.
I tried to change my password, but look at what it writes on the first line.
Which key do you think it is since I don't know what language I'm in anymore????

Hello,
Disconnect the keyboard ribbon inside the computer, then connect an external keyboard (not tested).

I am unable to navigate the BIOS because of this keyboard issue.As for unplugging the laptop keyboard, that exceeds my skills ☹️

If I cut the wire to disable the keyboard but that's not the problem, will I be able to reattach it later?
The repairman will be the last resort; it's an old computer and the costs would exceed the market value of the laptop.
Thank you for your help, I'm from Quebec... I'm going to sleep a bit and continue tomorrow. I've almost finished looking at all the keys with no success; the problem persists ☹️

Perfect, I won't cut anything! I'm going to try to disable it ☹️ Thank you all for your help... It's not done yet, it's not easy to gut...

Hello, if you think it's a virus, you can always enter the BIOS before startup and launch safe mode or format it via the BIOS (press F11 or Del during startup).

Thank you madmike for your help and advice. I also doubt that it’s a virus. At first, I thought it was, but now it seems to be a hardware problem.
I continue to ponder whether it’s worth repairing.

Gengengen · Answer

I have gutted the beast... Here’s a photo, is this the wire to unplug to try an external keyboard? Thank you

Continuation: I managed to disconnect the keyboard and enter safe mode to run an antivirus. I was infected. Could this have affected the keyboard? Thank you all for your valuable help ????
