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:http://peppermintos.info/dl2/Peppermint-3-20121105-i386.iso
or see here:http://peppermintos.com/download/
Once you've got the ISO image .. download Universal USB Installer (version 18.104.22.168 or higher) from here:http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/
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 downloadedStep 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
.. 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
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.
