No matter what you do online, you should always try to follow general good security practices:

• Be very careful with your personal data;
• Respect the privacy of others on the internet;
• Only download files and install software from known and trusted sources;
• Regularly update all software and operating system of your devices to reduce the risk of attacks;
• Create unique and complex passwords and securely store them in password managers;
• Enable multi-level authentication for your online accounts wherever possible;
• Use anti-virus/anti-malware software;
• Encrypt everything you can encrypt;
• If you have to use a public computer, try not to leave any traces (e.g., downloaded files, account logins, browsing history) behind;
• If your USB flash drive was in a public or unprotected computer, be sure to scan it with anti-virus/anti-malware software before using it again. It is generally recommended that portable devices, e.g., USB flash drives or external hard drives, are scanned each time they are connected to a computer;
• Take into account the consequences of your every action on the internet; privacy does not mean less responsibility;
• At least quickly read through the Terms of Use/Service before clicking "I accept".
