Always log out of the bank, credit card, and merchant sites after you have completed your transaction.
Do not allow your computer to store user names and passwords for merchant or banking websites
When setting up security questions for sites online, use false information unrelated to your personal information, and keep track of your answers.
Do not share your details with anyone- Your bank will never ask for your confidential information via phone or email. So, whether you get an apparent phone call from the bank or an email requesting your details, do not give out your login information. Use your login ID and password only on the official login page of the bank, which should be a secure website. Look for 'https://' in the URL when logging in; it means that the website is secure.
Install latest security software-The internet is full of malware, spam, and spyware. These software programs can damage your computer. It is necessary to keep your operating system up to date with the latest security software. Install these only from a trusted source. Using an ad-blocking software and a spyware detection program are some ways to prevent online fraud. Run virus scans regularly and keep these programs updated.
