Ask HN: Is there help for someone extremely afraid of computer viruses?

In 1995 I was in college at the computer lab and all the machines ran windows 3.1 which could exit back to a DOS prompt. The woman behind me accidentally did this. The directory DOS happened to be in was the virus protection software named simply "virus" so the DOS prompt read "C:\virus" and she got up and screamed "THERE'S A VIRUS ON THIS COMPUTER!"

1. Make sure they have a strong password that they don't use for any other sites.

2. Make sure they have 2 factor authentication turned on. If their bank doesn't support it, find them a new one.

3. Get them a Chromebook and make sure they don't install sketchy extensions or train them to bank in incognito mode (disables extensions by default)

Live boot cd or dvd. A finalised cd or dvd is pretty safe. They can switch back once their done all the important things that need logons.

I presuming that they fear losing their life savings, or more. Maybe there could be some type of insurance that would assuage their fear?

Ipad or ChromeOS?
