I noticed that when I turn on my laptop, a program like this almost always comes up and then goes straight back! I'm scared and please give me tips on what I can do about it.
First, check whether it is malware at all, for example with a scanner of your choice.
It doesn't have to be a hack, it can also boot from windows
If he was really hacked and the hacker is not stupid and has done his "job" well, you can do little there
Think about it logically: why would someone hack your laptop? Nobody hacked him because there's no reason to. If anything, you have a virus. Connect another hard drive to your laptop and boot wondows on it. Now you can format the hard drive on which the virus is on and then reinstall windows
Sounds like CMD that opens, why I don't know of course, anti malwarebytes should help out.
Nevertheless, the same thing: format hard drive.
Applies * smaller.
If someone had hacked your computer, you would not see such behavior. (At least if it's a hacker and not a bungler).
Usually these are auto-start programs, e.g. B. Check for updates.
