-I'm saving my files to the same location (on D: drive) - one folder for pictures and videos, one for music etc. I see no reason using backup software since I know what changes I make and copy them to external drive.
-Comodo Dragon is secondary browser. I was having some issues with Chromium (caused by CIS Auto Contaiment)
-I've already replaced the Adblock with Ghostery only and my browser got faster.
-I've changed UAC to always notify. I've also put a password request when it prompts. It uses my account to authenticate.
-I don't have much trust to cloud services. I only use OneDrive for my school documents and it works fine.
I've scanned my PC with EEK, it only found leftovers from Kaspersky's quarantine (which I forgot to clean )
