How can I ensure the security of my online purchases and prevent credit card fraud?

1. Review websites for information security features such as secure HTTPS connections, encryption, privacy policies, and payment processing.
   
2. Check the URL of the website to make sure it is secure and has no mistakes in spelling or other indications of a fraudulent site.
   
3. Update your antivirus software regularly to help protect your computer from malicious software.
   
4. Pay with a credit card or other secure payment methods instead of a debit card.
   
5. Assess the reputation of the business by reading customer reviews and learn about the terms and conditions of the purchase.
