When we already have a good computer it is much easier and cheaper to just get a bootable DVD or USB drive or make one if you are so inclined.
DVD with Linux boot-able all ready to use - $5.95
USB drive already made up $14.95
Download and make your own - Cost of one DVD or USB drive.
Used or new Windows 10 computer or tablet about $100 give or take a bit.
We use our primary computers, Windows 10 and Quicken Home and Business for banking. All of ours have Windows Defender and Malwarebytes Premium (MBP) on them. Go here (https://www.malwarebytes.com/) and see that MBP
does it all:
Malicious website protection
Pretty impressive for much less than the others that cannot run in tandem with Windows defender which is free. Then just never click on any spam. I get a lot now from Yahoo.com mail and am blocking their domain now as I know only a few folks that used it that I know. I review all the blocked emails in my junk folder before I empty it because it occasionally catches valid emails.
I get criticized for talking too technically or over heads. I just tried to follow the directions to create a Mint Cinnamon USB drive from the link I gave and it won't work so I will rewrite that post too in an edit.
I was unaware that you can order a USB drive already burned and ready to boot from here: https://www.osdisc.com/products/linux/linuxmint/linux-mint-182-cinnamon-16gb-usb-flash-drive-32bit.html
Or you can just get the live DVD for $5.95 here.
