The screen of my laptop is always white when you start up and you can't discover anything anymore. But when I connect the laptop to an external monitor, everything is normal on the external monitor. Before this problem I had problems with Kaspersky, because he always told me that he found a Trojan. But when I saw where this Trojan is, he specified Location: System Memory. Did someone have the same problem or does someone have a suggested solution? I would appreciate an answer!
You can indeed remove the virus on the external screen (if possible).
Otherwise, I can't help you much there.
If the virus is not found,
You can save all important software and apps to an external hard drive (or storage device such as USB stick, CD) or Google Drive and reset your Winows.
Manual:
(Instructions may differ on versions of Windows other than Windows 10. Only use if it is certain that a virus / Trojan is on the computer, only apply if the actual screen is really broken and therefore shows only white.) Can have risks.)
IMPORTANT: Store all important files, apps, etc. In Google Drive or other storage media.
Open settings
Click Updates and Security
Go to restoration
Click on "Reset this PC"
IMPORTANT: Click Clear All Files. (Because you've already stored your important documents and apps etc. Somewhere else, because if you click on keep your own files, you take the virus with you.)
Wait 1 - 2 hours and the screen should work again.
