I use a hypervisor with snapshots, so don't technically need an AV... as my system is a clean install every time I turn it on... unless I let it do updates & create a new snapshot.
(this lets me run a virus that wipes everything from my PC or encrypts it all... turn it off/on... and everything is back to normal)
My documents are spread over GoogleDrive, OneDrive and a local Git repo (with versioning)... encrypted with Cryptomator, so I have redundant backups to only the specific files that I'm using at the time.
All passwords are split and stored partially in a KeePass file (via the "cloud" drives) and partially in an offline tablet that has had its wifi device unplugged (with 2FA on anything that supports it), so no single point of failure.
I was just testing Avast to see what it was like, as I've not used an AV in over 10 years...
...but its really falling short.
It's not even been able to detect that its running inside a virtual environment with other OSes :/
Avast's main focus seems to be on telling me that I should be using their VPN... probably so that they can watch my visits to any unencrypted sites (and how I interact with them) for marketing purposes :/
