This is a list of software programs that are not required to be "installed" onto a computer's permanent storage device to be executed, and can be stored on a removable storage such as a USB flash drive and used on multiple computers. Ideally it can be configured to read its configuration from the same location as the software. This should not be confused with software portability, which is the ability for software to be run or compiled with little modification on diverse computing platforms. Most software on this list can be run on multiple computers of the same hardware and operating system platform only.

- Use a solid antivirus program on your primary PC and keep its virus definitions up to date.
- Scan your PC and portable drive for viruses on a regular basis.
- Whenever you plug your portable drive into an unknown computer, you should assume that it may now be infected with a virus. If the PC has a virus that is currently in memory, it may attempt to infect your portable applications as soon as you plug it in.
- When you then plug your portable drive into another computer (after an unknown), you should first scan it for viruses before running any of your applications. (Most antivirus software will make this available to you by right-clicking on your drive in Explorer or My Computer.) That way, if it is infected, you'll know before you run your applications and the new computer will not be infected.
- Always wait until the drive access light has stopped blinking and then click the icon in your system tray to 'Safely Remove' your device. Don't just remove it. Just because the portable app's window is closed doesn't mean the app has fully closed and finished writing to the disk.
- Back up your portable applications on a regular basis.
