My laptop is taking screenshots on its own and saving the on OneDrive. Sometimes a few pics, otherwise scores of pics per second get saved. How is this possible? Please advice.

Hello Joel,

I am Jaspreet Singh.

One reason could be if your are accidentally pressing the print screen button on your keyboard ( or the key that takes screenshot for your device as this may be different) confirm the key that does this in your system and check if you are pressing it.

For the save part OneDrive has an option to automatically save screenshots to its storage and it can be turned off via these steps :

That being said automatically taking screenshots is one symptom of a device affected by RAT ( remote access Trojan) if you are sure the screenshots are not triggered by your actions use a free version of malware and run a complete scan. Also check the applications that are installed in your system through control panel app list and also extensions on your installed browsers.

Hello I am Richard. You might have been accidentally pressing your screenshot button (as Jaspreet said) or it could be a trojan or a RAT which can let the attackers controll your computer. First I would recommend to scan your device with Windows defender using the offline scan mode. However if it did not find anything I would also recommend trying the free version of malwarebytes. However if it still could not find anything check installed apps in the control panel or the settings app if you wish and then look for new apps that you may have knowingly installed but it was packaged with the R.A.T. Also try to check for faulty browser extensions (check all your browsers & internet explorer if you are on Windows 10). Maybe try to look through onedrive to see if any personal info was screenshotted. Hope this helps.
