A lot of problems out there arise due to viruses on the computer hard drive makes the wallet installed in it vulnerable to attack. Therefore, I suggest separating wallets and PC, which are often used for browsing to avoid or at least provide security.
Buy hardware wallet is the best choice, but when you don't have enough money to buy it?
I think we can use USB Flashdrive to make a portable operating system included Electrum wallet.
What we need?1. Tails Os - download
https://tails.boum.org/install/dvd-download/index.en.html2. Rufus - download
https://rufus.ie/3. A USB flash drive a minimum of 8 Gigabyte (fat-32 formated)
How To Install?a. inject your USB flash drive into PC
b. Open Rufus
- 1. USB flash drive will automatically be detected when Rufus application has ready
- 2. Click select and choose where your file downloaded
- 3. Move your cursor to make persistent partition size
- 4. (Optional) Labeling your USB flash drive
- 5. Click start

- 7. Reboot your PC while push esc button on keyboard (depends what PC are you using. sometime f9 and f11) then booting with USB Flashdrive
- 8. Star your tails and wait for a while.
- 9. let's make configuration your system like a persistent password. This important part to safe your data because tails os won't keep your setting when you restart it.
NOTE: This is a crucial thing to keep and encrypted your data on persistent. also, you have a choice to enable or disable it.

By the way, Tail OS has already installed an electrum wallet, but not recommend because we can't verify it.
