We all have the need to use a public computer here and there. Public computers can be found everywhere, at the library, school computer labs, hotel and cruises business centers, Internet cafés, etc. We need them to log into our accounts to check email while on travel, download documents to print, or open websites our mobile phones cannot handle. All is great until we forget to log off our accounts or delete downloaded files left behind in the computer. The next person who uses the same computer or device may end up intentionally or unintentionally accessing and tampering with your data.
Also, next time you are using a public computer, make sure you clear the clipboard (copy/paste) after you are done using it. If you don't know how to, just type something and then copy it, that should replace the previously copied item with this last one. It is also recommended to clear your Internet browser history. You can typically find this as an option on the top horizontal menu of every browser. If you have the option to delete "cookies" go ahead and do that as well.
If you need to log into an account, pay attention not to select the option of "remember this password on this computer" when prompted. If you accidentally select the option search for the "keychain" feature on the computer to delete your entry. Use a copy/paste method if at all possible and available to enter passwords. Some public computers may have malware programs installed designed to record your every keystroke, exposing everything you type to the bad guys.
If you downloaded anything, make sure you check the Downloads, Documents or Desktop folders for any of the files you may have downloaded and delete them. If you can't find them open the search feature and try locating them.
Overall, avoid logging into your sensitive accounts like your bank account, your credit card accounts, your email, etc. and refrain from making any purchases that will require you to enter your credit card number or other private information.
