How to prevent phishing: In simple words, phishing means taking your confidential information by deceiving. You must have received email asking you to fill up To protect your confidential data from stealing you can follow the following steps:

If you receive an email asking for fill up with your personal information, then do not give then any information. Even if you receive any email from your bank, then call them personally to make sure that they have actually sent that email. Even if you follow the link of the phishing email and see that the website looks like the same of your bank site or any other familiar site, do not take it for granted. Because it is possible to make the exact replica of any site to fool you.

If you take a careful look at the URL, then you may figure out the real identify-it will be very similar to you familiar site, but not the exact. For example if you follow a link to buy a watch online and the site looks exactly the same as Amazom.com, then take a look at the URL if it is http://www.amazon.com then ok, otherwise it is false. The fake URL can be http://www.amazom.com or anything very similar to that.

  • Make sure that your web browser is updated.
  • Check your anti-virus log file to see if there are any phishing reports.
  • If possible, check your credit card and debit card transaction or any other online transaction statements to make sure that there are no illegal transactions
  • If you have to purchase anything only always try to use the secure transaction process. A secure transaction URL will always start with https:// not http://

Finally, always use Internet security software and keep your operating system and web  browser updated with the latest security patches.
