My advices for your "Security" config:
1. (as exterminator20 already mentioned) Enable UAC at least to minimum - default till maximum preferred.
2. (as exterminator20 already mentioned) Enable Windows SmartScreen to default/recommended.
3. Hold your system (especially Windows, Windows Defender, Browser and Extensions) up to date
4. Download and install any second opinion malware-scanner to scan your system regularly without realtime-protection (recommended:
Zemana AntiMalware (Free),
Malwarebytes Anti-Malware (Free),
HitmanPro (30 days trial - commercial)
5. Don't save your passwords in any unencrypted text file or on your browser without setting up a master password. Use a pencil and paper to write it down or use a trusted and reputable password manager.
6. Replace Adblock by
uBlock Origin (recommended) - it's also for free but with much more security.
7. Do regularly backups of your system, by using Microsoft OneDrive or any 3rd party Backup-Software (e.g. O&O Disk Image, Acronis TrueImage)
If you have any questions, how to do all this steps, feel free to ask.
