The following instructions are for creating a PeppermintOS Three LiveUSB (without persistence) stick using a Windows PC … if you need instructions for creating one on a Linux PC, let me know.
On your Windows PC, download the PeppermintOS (Three) 32bit ISO image from here:
or see here:
Once you’ve got the ISO image … download Universal USB Installer (version 188.8.131.52 or higher) from here:
Start Universal USB Installer, and at …
Step 1 … In the drop down list, select PeppermintOS (Three)
Step 2 … point it at the ISO image you downloaded
Step 3 … Choose your (already plugged in >= 1GB) USB stick … probably best to let it format it too, so backup its contents first.
Step 4 … Set the slider to the ZERO
Heres a pic of the Universal USB Installer interface
Click Create … and wait till it’s done … it will take a while, and may appear to have stopped … but just wait till it says it’s “Done” … as in the following pic

Once the LiveUSB has been created, click Close, plug it into your AA1, then turn ON your AA1 … as soon as you see the first screen (Acer Empowering People), hit the F12 key to access the boot device selection screen … and select the USB HDD as the drive to boot from and hit Enter to boot.
When asked, select “Try Peppermint” not “Install Peppermint”
Be aware … running from a USB stick will be quite a bit slower that running it from the internal SSD, but you’re only going to be using it for the occaisional banking/buying.
As I said, it’s unlikely Peppermint was the problem in the first place … but this Peppermint LiveUSB will be unable to save any changes, so it will be impossible for malware to get installed and persist across a reboot.
You’ll still need to be VERY careful with checking URL’s in the browser … and preferably don’t go visiting any other sites besides the one you want buy/bank on first (ie. boot, open browser, go DIRECTLY to the site you want to bank/buy from).
For even better security whilst banking/buying …
Boot the LiveUSB you just created, and don’t set up a wireless connection … connect to your router with an ethernet cable.
