security for desktop app

Hi there @asukulu

1Password can't be any more secure than a device that's compromised. You should keep up to date with your computer's built-in malware protection (Microsoft Defender) and make sure it runs routinely to check for problems. 1Password has to work on the understanding that it's running on a device that isn't infected, and making sure it's not infected is a job for Microsoft Defender, or some other anti-malware software if you choose to use something else.

This article from Microsoft may help as a starting point: Getting started with Microsoft Defender - Microsoft Support.

Please let me know if you have any questions, or would like any further help.
