how can i check if the website is fraud or not

A web-address which looks OK might not be a legitimate site. Following measures may help you identify if the URL is legitimate.

• Incorrect or incomplete company name: e.g. spelling error like www.paytma.com or www.payt.com is not same as www.paytm.com.
• Before entering any information, make sure your browser is showing the padlock symbol next to the address bar and that the address starts with https://. Without these signs, there’s no guarantee of security or encryption of your details.
• Cheap-looking sites – Fake sites masquerading as big brands don’t necessarily have the time and investment dedicated to them as the real thing.
• Do your research – If you haven’t used a website before, check its credentials. Search for alternative contact details such as address or phone number – if in doubt, call them first.
• Trust your instincts – If a deal seems too good to be true, it probably is. If you ever feel a site isn’t legitimate, don’t enter any personal information, and leave immediately.
• Be wary – If a site you regularly visit seems different, double check that it’s the real site.
• Update your software – Your internet browser includes security functions which can help spot sites masquerading as trusted sites, and can even tell you before you arrive that the site is a fake. Check that the security options are enabled in your browser.
