Suddenly several windows open

Suddenly, out of nowhere, dozens of windows open on their own. I close these windows and they keep popping up.

Sometimes when the computer restarts, at the home screen, before entering the password, the screen blinks and hears a noise as if someone was typing the enter key.

At first, I thought the problem could be virus or a malware. But the laptop was protected by a updated version o KIS. Nevertheless, I formated the laptop and installed a new OS and the same problem persists.

Did my solution solve it? Sometimes malware can be super sneaky. I may have created an invisible partition that you couldn't format.


No. As far as I know l have formated all partitions.


Hi @c.gomes,

Have you tried starting in safe mode?

Where is the cursor positioned when this happens? I'm wondering if you have a keyboard (enter key?) or touchpad problem. Has anything been spilled on the keyboard?


There has got to be malware... Format the drive in disk manager so that every single megabyte is accounted for. Delete all partitions, then format it.


Replying George A., I deleted all the hard disk partitions and installed a fresh Windows 7 Ultimate using an USB. So that, I guess that if was a virus or a malware it was completely removed.

Regarding jayeff comments, yes I guess that there is something that is not running well with the enter key and with the notebook touchpad. The problem is that some days ago I was using a wireless mouse, so I was not using the keyboard or the touchpad and several windows popped up endlessly. So I have no clue what is the problem. Sometimes, when I have a MS Office opened the cursor moves down real fast as I was pressing the enter key unabated.
