Malware Based Phishing is a scheme. This scheme occurs when the thief attaches a harmful computer program made to look helpful onto emails, websites, and other electronic documents on the Internet.
This type of computer program (Malware Based Phishing) is called malware. The malware uses key loggers and screen loggers to record your keyboard strokes and sites that you visit on the Internet.
The malware sends the information to the schemer who is located at another location using the Internet. An example of this type of phishing is an email disguised as coming from Norton Anti-Virus. The message prompts you to install an updated web browser to increase your computer security. You, click on the link and download the supposed updated browser but in reality you have just downloaded malware.
