Nortons is retarded. Disable all your AV stuff, never use it again. These commercial AV software companies CREATED THE VIRUSES they eliminate. Use clamAV instead its open source

Use linux not windows. Or apple. Don't use windows. Do not....use windows.

Keep your system updated normally. Don't store any private info in your browser like passwords. Use a password manager with the db on a usb stick so you have to plug it in to use the pw mgr. Use it, unplug (airgapped)

Use privacy extensions

Don't download executables

Don't run untrusted executables

Run your browser exclusively within a VMware or equivalent VM

use linux

Run open source up to date AV once in a blue moon (clamAV is open source)

Run a rootkit detector but absolutely don't freak if it finds things, there are MANY false positives like with AV
