3. Perform a virus scan on the files/email attachments that you download before executing them.
4. Regularly Update your operating system and browser software. For a better security it is recommended that you surf the Internet through the latest version of your browser program.
5. Never share your password (email, bank logins etc.) with any one for any reason. Choose a strong password (A blend of alphanumeric+special symbols) and change it regularly, eg. every 3 months. Avoid using easy-to-guess passwords. (ex. pet’s name or kid’s name)
6. Always type the URL of the website in your browser’s address bar to enter the login pages. For ex. To login to your Gmail account type http://mail.google.com
7. Before you enter your password on any login page, ensure that you see https instead of http. ex.https://mail.google.com instead of http://mail.google.com. HTTPS protocol implements SSL (Secure Sockets Layer) and provide better security than a normal HTTP. For more information on HTTPS and SSL see Know More About Secure Sockets Layer (SSL).
8. Beware of phishing emails! Do not respond to any email that request you to update your login details by clicking on a link in the body of the email. Such links can lead to Fake Login Pages (Spoofed Pages). For more information on phishing refer What is Phishing?. Also refer How to Protect an Email Account from being Hacked.
9. Always hit the logout button to close your login session rather than abruptly terminating the browser window. Also clear your web browser caches after every session to remove the temporary files stored in the memory and hard disk of your PC.
10. Avoid (Stop) using any public computers or computers in the Internet cafes to access any sensitive/confidential information. Also avoid such computers to login to your email/bank accounts. You cannot be sure if any spyware, keystroke-logger, password-sniffer and other malicious programs have not been installed on such a PC.
